High Performance Hard Magnetic Films: From Model Systems to Micro-system Applications

Materials Science Seminar
Nora Dempsey, Institut Neel – CNRS, France
January 14, 2013 11:00AM to 12:00PM
Building 223, Room S105
High performance hard magnetic materials are of growing importance for clean energy technologies (hybrid electric vehicles, gearless wind turbines…) and have great potential for use in micro-systems. In this talk I will report on the preparation and characterisation of NdFeB thick films. On the one hand these films are used as model systems to study magnetization reversal, with the aim of guiding the development of heavy rare earth free magnets. On the other, they are being developed for integration into micro-systems. Some bio-applications of these micro-structured films will be presented.
