Particulate and Granular Magnetism

Kevin O'Grady is an internationally recognised expert in magnetic materials and in particular magnetisation reversal processes, having written over 300 refereed works on the subject. He is a former President of the IEEE Magnetics Society and is the founder of a small company, Liquids Research Ltd., based in North Wales, that manufactures Ferrofluids and other magnetic liquids.Gonzalo Vallejo Fernández received an undergraduate degree in physics from the University of Oviedo in 2002 followed by a PhD in magnetism from the University of York in 2007. After a two year post-doc at York, he relocated to the University of Glasgow as a Research Fellow. In 2010 he returned to York and joined the Department of Physics as a Lecturer/Assistant Professor in 2012. He is currently a Senior Lecturer/Associate Professor in the School of Physics, Engineering and Technology at the University of York.Atsufumi Hirohata received BSc and MSc degrees in physics from Keio University, Japan, in 1995 and 1997, respectively, and obtained his PhD in physics from the University of Cambridge in 2001. He then moved to the Francis Bitter Magnet Laboratory in the Massachusetts Institute of Technology in 2002 as a Postdoctoral Associate. He then became a Researcher at the Department of Materials in Tohoku University, Japan, in 2003 and at the Frontier Research System in RIKEN, Japan, in 2005. He became a Lecturer in the Department of Electronics in the University of York in 2007.
