Yasukazu Murakami is Professor of Kyushu University (previously, with Tohoku University). As an electron microscopist, Murakami is devoted to the studies of microscopic mechanisms underlying novel material functionalities and/or anomalous phenomena observed in crystalline solids. With respect to this research area, he has contributed to the studies of (1) pattern formation mechanisms in magnetic/nonmagnetic shape memory alloys [Phil Mag Lett: 2001, Acta Mater: 2002, APL:2003, 2008] , (2) nucleation and growth process of the ferromagnetic metal phase in hole-doped manganites [Nature: 2003, PRL: 2004, Nature Nanotech: 2010], (3) charge ordering in transition metal oxides [PRB: 1997, 2010, 2012], and others. He is also interested in the development of new techniques of electron microscopy. His achievements include (1) separation of the magnetic information form the electric information in electron holography observations [Nature 2003], (2) simultaneous measurements of structure, magnetisms and conductivity [APL: 2006], (3) determination of magnetic parameters from nanometer scale area [Nature Nanotech: 2010], and such other techniques.
