Chandrima has really helped us advance fast opto-magnetism in our group and opened up new ideas and ways of working. We wish her every success in her new work on ultimate attosecond investigations of magnetic materials and we look forward to continuing to cooperate with her in the future.
A virtual goodbye party for Chandrima!
Rhian-Marie Thomas awarded an OBE
Rhian, the only Welsh speaker ever to work in our Group, joined Barclays Finance in 2000 just after completing her PhD on mixed valence manganites. She came to understand that finance was more than more than matchmaking willing lenders with willing borrowers, but along with Science, probably the most important tool for reshaping the world. She became a passionate advocate of the green agenda to combat climate change and is now CEO of the Green Finance Institute. Find out about it here and listen to her 40-minute interview of Mary Robinson here . The OBE is a British honour for people who have contributed to the arts, sciences or public service. Only about one person in a thousand ever receives such an honour.

Joule was right! A new contribution to Nature
175 years ago, James Prescott Joule, a successful Salford brewer who was passionate about science, immersed an iron rod in water. Joule is famous for showing that different forms of energy - thermal, mechanical, electrical - are interconvertible, and the modern unit of energy bears his name. But just then he was interested in magnetism, and he used an electric current in a coil to magnetize his iron rod, while monitoring carefully the change in water level to infer its volume change. Earlier he had detected a small increase of length when the rod was magnetized, a discovery known as magnetostriction, which explains why a low hum at twice the mains frequency emanates from transformers. But that day, when he was looking for volume change, he found — nothing. Joule reasoned that when the rod expands as it is magnetised along its length, it must contract by half as much in the perpendicular directions . This is volume-conserving ‘Joulian magnetostriction’. Over the years, better magnetostrictive materials than pure iron were discovered, and many useful applications were found, ranging from electric toothbrushes to underwater sonar. One of the best materials was an alloy of iron and gallium, discovered in a US military laboratory in 2000 . Its magnetostriction was found to be up to 50 times greater than pure iron. Magnetized rods could expand by up to 0.1%, a giant amount of magnetostriction. Then, in 2015, two US scientists claimed in a letter to Nature  that the giant magnetostriction of iron-gallium did not conserve volume, as everyone had expected. This provoked some of the leading researchers in the field, including Chengbao Jiang and his student Yangkun He at Beihang University in China to grow a dozen crystals of the alloy (metals can form crystals!) with different compositions, shapes and heat treatments. Together with colleagues Michael Coey and Plamen Stamenov at Trinity College, Dublin they measured the dimensional change for every possible combination of crystal orientation and magnetic field direction. They even repeated Joule’s original immersion experiment, but they too found — nothing. Joule was right! They announced in a short note to Nature  that the theoretical basis of magnetostrictive technology was sound! A spin-off from the Ireland-China collaboration is a 4-year project, supported from both sides, to develop a new, microscopic energy-harvesting device based on the Chinese iron-gallium crystals. It will convert mechanical energy to electrical energy wherever if can tap a source of mechanical vibrations. Joule would have been proud!

Magnetic switching without a magnetic field
Magnetic and electric switches underpin the information revolution. The magnetic switches are tiny patches of magnetic material that store the information; they can be magnetized in one of two opposite directions ‘up’ or ‘down’ to represent the binary digits ‘0’ and ‘1’. Everything we download daily onto our computers or mobile phones is stored magnetically on millions of spinning discs located in data centres scattered across the world. Unfortunately, writing and erasing all this information currently needs a magnetic field to switch the magnetic bits. These fields are produced by passing current pulses through minute coils, consuming vast amounts of energy in the process. Now a team in the Magnetism and Spin Electronics Group at Trinity College Dublin have devised an elegant scheme for magnetic switching that does away with any need for a magnetic field. Two PhD students, Yong Chang Lau from Malaysia and Davide Betto from Italy, working with senior researcher Karsten Rode and physics professors Michael Coey and Plamen Stamenov publish their results in the prestigious journal Nature Nanotechnology this week . Their device consists of a stack of five metal layers, each of them a few nanometers thick. At the bottom of the stack is a layer made of platinum, and above it is the iron-based magnetic storage layer just six atoms thick. Platinum is a favourite of researchers in spin electronics (also known as spintronics), the technology that makes use of the property that each electron is a tiny magnet. Passing a current through the platinum separates the electrons with their magnetism pointing in opposite directions at the top and bottom surfaces. Those pumped into the storage layer try to switch its magnetic direction, thanks to an effect known a ‘spin-orbit torque’ that follows from Einstein’s theory of relativity. But like a pencil balanced on its point, the magnetism of the storage layer doesn't know which way to fall. The team designed the rest of the stack to solve that dilemma by acting like a nanoscale permanent magnet that creates the small field necessary to make the switching determinate, at zero cost in energy. The Group now plan to demonstrate a full memory cell, and an ultra-fast oscillator based on spin-orbit torque and layers of a novel magnetic alloy they developed recently. The thin film device stacks will be grown in a new SFI-funded thin film facility in the AMBER Centre at Trinity’s CRANN Institute for nanoscience. These new spintronic devices have potential to deliver the breakthrough needed to sustain the information revolution for another 25 years.
Trinity Physicists Capture Magnetism from Empty Space
14 March 2016
Theoretical physicists have long believed that empty space is not a formless void. The vacuum is thought to be seething with zero-point energy, the inevitable quantum residue of every sort of electromagnetic radiation. Nobody has ever managed to find a way to tap this limitless store of energy, and the signs that it even exists are slender. Direct evidence is mainly based on a tiny shift of a few parts per billion in an energy level of hydrogen, discovered 70 years ago by Willis Lamb in the USA, and a minute force between metal plates when they are only a few nanometers apart in vacuum predicted around the same time by Dutchman Hendrik Casimir.
Now, a team of scientists from the School of Physics working in Trinity College Dublin’s Centre for Research on Advanced Nanostructures and Nanodevices (CRANN) have discovered a new and unexpected manifestation of this elusive energy. In a study of cerium dioxide nanoparticles – mainly used in catalytic converters that control toxic exhaust emissions from automobiles – Professor Michael Coey, his former PhD student Dr. Karl Ackland and Dr Munuswamy Venkatesan came across a strange magnetic effect. Quite unlike the behavior of normal magnets like iron, the effect did not vary at all with temperature. Stranger still, the magnetism only appeared when the particles were clumped together. Separating them into smaller clumps by diluting with nonmagnetic nanoparticles destroyed the magnetism.
In a paper published on-line today in Nature Physics, the team that was completed by Professor Siddhartha Sen, a quantum field theorist renowned for his brilliant lectures in Trinity’s Mathematics Department, reported their findings, and came up with an astonishing explanation. Electrons in the clumps of tiny particles were responding to the vacuum electromagnetic field. Sen and Coey had recently predicted that such behavior might be possible in systems with an enormous surface area – a milligram speck of the cerium dioxide nanoparticles has as much surface area as an entire sheet of newspaper. Furthermore they predicted that when the particles were separated out into regions smaller that the wavelength of the light associated with them, the effect would disappear. This is exactly what was observed.
As with any fundamental discovery in science, it is difficult to predict where this could lead. Others will want to test the results. The theory shows that effects can only be expected when there is a huge surface to volume ratio, as in the thin layers of interfacial water attached to biomolecules. Sen is already beginning to apply the ideas to protein folding. The zero point energy may never power our cars, but it might be shaping our lives. • Collective magnetic response of CeO2 nanoparticles, M. Coey, K. Ackland, M. Venkatesan and S.

Michael Coey wins prestigious Gutenberg Prize. Strasbourg 23/01/2015
At a ceremony at the University of Strasbourg, the president of the Cercle Gutenberg, Professor Pierre Braunstein, announced the winners of the 2015. Gutenberg prizes and visiting professorships. Michael Coey, who will be carrying out a project on ‘Microfluidics without walls’ in collaboration with Bernard. Doudin of IPCMS and Thomas Heremans of ISIS was honoured, together with Veronique Dimier of Université Libre de Bruxelles whose project is on the ‘Influence of former British and French colonial administrators on the EU’s development policy in Africa’ and Giovanna Guidobon of the University of Indiana, whose project is on ‘Mathematical modeling of the circulation of blood in the brain’.
The Cercle Gutenberg, consisting of Nobel Laureates and Members of the French and other Academies of Science based in Alsace, has selected three Laureates every year since 2007. The award is €60,000 of which €50,000 is used to help support a research project at the University of Strasbourg. Michael Coey’s project aims to revolutionize microfluidics, an emerging technology that handles minute quantities of liquid reagents in channels about 100 microns wide for applications like in vitro diagnostics and new drug discovery. By using magnetic liquid confinement instead of solid walls to define the fluid channels he expects to overcome the main drawbacks of the technology – clogging, sluggish mixing and inflexible operation, thereby giving birth to a radical transformation of the ‘Lab on a Chip’.
Researchers discover world-first new material which could revolutionise information technology
New ‘MRG’ material could lead to superfast technology and energy efficient data storage 25 years in the making and discovered by researchers at AMBER, Trinity College Dublin Scientists at AMBER, the materials science centre based at Trinity College Dublin have discovered a completely new material, which could revolutionise information technology, computer processes and data storage. The world-first discovery was led by one of Ireland’s most highly-cited researchers Professor Michael Coey, a Principal Investigator at AMBER from Trinity’s School of Physics. The Centre is funded by the Department of Jobs, Enterprise and Innovation through Science Foundation Ireland. The research group led by Prof. Coey has created a completely new alloy of manganese, ruthenium and gallium, known as MRG. MRG is a strange new magnet; internally it is as magnetic as the strongest magnets available today, yet seen from the outside it barely appears magnetic at all. This world-first material (technically known as a “zero-moment half metal”) will initiate a completely new line of materials research and could open up numerous possibilities for electronics and information technology. The potential applications of MRG are many. It could lead to limitless data storage, resulting in huge, superfast memory in personal computer devices. It could also eliminate the potential of external magnetic forces to ‘wipe’ computer data. Finally, MRG could have major implications for the Big Data revolution. Commenting on the discovery, Michael Coey said, “Magnetic materials are what make reading and storing data – either on personal devices or on large scale servers in data centres – possible. Magnets are at the heart of every electronic device we use – from computers and laptops to tablets, smartphones and digital cameras. Given its unique insensitivity to magnetic fields, and the tenacity of its internal magnetic properties, MRG could now revolutionise how data is stored, which could have major implications for the future development of electronics, information technology and a host of other applications.” For 25 years, researchers worldwide have grappled with how to create a magnet such as MRG by trying to arrange numerous combinations of atoms in a way which was difficult without flouting the basic principles of physics. Now, AMBER researchers have solved this problem, by using established industry-standard processes for making the electronic circuits on silicon chips. MRG could therefore be adopted by computer and electronics companies relatively easily. Minister for Research and Innovation Seán Sherlock TD welcomed the announcement and said, “Here is a Government-funded research centre discovering innovative solutions to problems faced by the technology industry. I would like to praise the work of Prof. Coey and his team on this world first which opens up a range of potential applications in the electronics and information technology sectors.” Professor Mark Ferguson, Director General of SFI and Chief Scientific Adviser to the Government of Ireland said, “SFI Research Centres like AMBER, were established with a focus on delivering cutting edge, internationally excellent research, which will deliver real benefit to the economy and to industry. This discovery absolutely fits the bill and I congratulate Professor Coey and his team. Their discovery is a world first which could solve one of the major problems faced by the technology industry worldwide. This is the type of research which Ireland is, and will continue to be recognised for.”
