Additional information

Novel demonstration that NdFeB grain boundaries can be used to achieve high coercivity permanent magnets, a possible route to reduced rare-earth high-performance magnets in hybrid cars. The work was carried out with partners including IFW-Dresden, Neel-Institute Grenoble, University of Sheffield, Toyota Japan. Notably, we patented this with Toyota (Patent No. 10306166.9 – 1215) who now use this technology in a major market leading product. I have given invited talks at MISM,Moscow 2011, MMM Phoenix,USA 2011, TMS-meeting USA 2011, REPM meeting Nagasaki, Japan 2012. Toyota has awarded £225k in follow on funding for work on temperature-behaviour of NdFeB. yano@masao.tec.toyota.co.jp
