Group-D Reunion at the INTERMAG 2017 Conference in Dublin

The Group-D reunion at INTERMAG 2017 was a great opportunity for the past and present members to meet. Special thanks to Dr. Nora Dempsey for the organisation of the evening.


SFI Funded Trifolium Dubium sputter-deposition tool update

The Spin Electronics and Magnetism group at TCD will soon take charge of a new National Access vacuum deposition and analysis system, fully integrated for the use of various deposition and analysis techniques without the need to break vacuum. The system, developed by DCA Instruments, Finland, will employ sputtering of metals and dielectrics, pulsed laser deposition (PLD), and molecular beam epitaxy (MBE). Also included will be an X-ray photoelectron spectrometer (XPS), developed by SPECS, Germany. Each technique will be housed in its own chamber, with separate chambers for sputtering of metals and of dielectrics. Various technologies will be available during deposition, including confocal and target-facing-target sputtering, DC/RF and reactive sputtering, combinatorial and wedge deposition, substrate biasing, high temperature oxygen-compatible heaters, natural and plasma oxidation/nitridation of metal layers, with quartz crystal monitoring of deposition rates. RHEED analysis will be available in PLD and MBE chambers. All chambers will be connected via a UHV central hub, with entrance via 10-wafer loadlock. Automation will allow for high throughput and efficiency.

The new system is expected to be fully commissioned by the end of March 2018.


2017 INTERMAG Conference takes place in Dublin from 24th – 28th April

Fourteen hundered scientists will be coming to Dublin in April for this year's INTERMAG conference. Group members, Michael Coey, Plamen Stamenov, Karsten Rode and Gavin D'Arcy are all belong to the local committee. Present and former group D members will get together at a special event on the Thursday, 27th April. Details from Kat at siewierk@tcd.ie.


Plamen Stamenov coordinates FET–OPEN TRANSPIRE Project

TRANSPIRE, Ireland's first project to be funded by the EC Future and Emerging Technologies Program with partners in Germany, Norway and Switzerland, runs from 2017 to 2020. The €4.2M budget will be used to develop Terahertz spintronic chip–to–chip communications based on spin–torque oscillators, which are based on new half–metallic thin films discovered in the group.


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’.


Hongjun Xu wins the 2013 CRANN Image Competition

Hongjun Xu has won the 2013 CRANN Image Competition for his picture How does science start? The image is of a CVD grown nickel-graphene sample, and the colour was added.

Hongjun is the third member of the group to win CRANN Image Competition. Amir Esmaeily won in 2012 and Lorena Monzon won in 2011.

Michael Coey wins Humboldt Research Award

Professor Michael Coey is the recipient of a 2013 Research Award from the Alexander von Humboldt Foundation. The Foundation grants awards to internationally-renowned senior academics in any field in recognition of their entire research career. Prof. Coey has been granted €60,000 to pursue research on rare-earth free permanent magnets with Prof. Claudia Felser of the Max-Planck Institute for Chemical Physics in Dresden.


Professor Michael Coey nominated to European Academy of Science

Professor Michael Coey has been elected to the European Academy of Science (EURASC). The European Academy of Science is an independent organisation that aims to promote excellence in science and technology. Based in Belgium, its members include Nobel Prize and Fields medal winners and some of the best European scientists having a vision for the scientific, economic and social future of Europe. Prof. Coey is the first Irish member.


Dr. Lorena Monzon secures Enterprise Ireland funding

Dr. Lorena Monzon has secured funding of €112, 911 from Enterprise Ireland for a one-year project beginning on 1st August 2013. Her project aims to improve the electropolishing process of medical devices, in collaboration with industrial partners.


New electron beam lithography system to be installed in CRANN

A dedicated electron beam lithography system is to be purchased and installed in CRANN. Electron beam lithography is a well-established top-down research method for creating nanoscale thin-film structures. It is versatile, and can be used for single nanoscale devices or large arrays of nano-objects. E-beam lithography complements UV lithography, which is used for micron-scale devices and structures.

The system is an Elionix 7700 75keV which we are acquiring from Notre Dame University in the USA. The tool has a laser stage for precise alignment and 10nm lateral resolution. Funding for the purchase and installation has come from the TCD-SFI Opportunistic Fund, and from CRANN.


Plamen Stamenov receives special SFI award

Prof. Plamen Stamenov has been awarded a Starting Investigator Research Grant (SIRG) by SFI 2012-2017 (€ 500 K). This project will advance the Andreev reflection technique, a type of point-probe superconducting spectroscopy, which can be applied to determine spin polarization in many magnetic materials and device structures.
