Professor John Coey

Professor Emeritus (Physics)

 

Deputy Director & Principal Investigator (CRANN)


Prof Michael Coey has degrees from universities in the UK, Ireland, France and Canada. After gaining his PhD in 1971 he was appointed Chargé des Recherches with the CNRS (Grenoble) and was visiting scientist at the IBM T. J. Watson Research Centre (New York) before moving to Trinity College Dublin in 1978, where he became Professor of Experimental Physics in 1987, and took up his present chair in 2007. He founded Magnetic Solutions Ltd. in 1994, and co-ordinated the Concerted European Action on Magnets from 1985-94. His SFI-funded project on Conception and Implementation of Nanoscale Spin Electronics (CINSE, 2001-2006) was followed by Magnetic Nanostructures and Spin Electronics project (MANSE 2006-2010.) Honours included the Charles Cree Medal, Institute of Physics (1997), the Gold Medal of the Royal Irish Academy (2005) and an honorary doctorate from Grenoble (1994). He has developed novel permanent magnets and contributed to the understanding of magnetism in both amorphous and natural materials. Current interests are centred on novel magnetic materials, spin electronics and the influence of magnetic fields on chemical and biological processes. An authority on magnetism and its applications, Prof Coey is the author of more than 500 scientific papers, 20 patents and several books.
