A research group led by Associate Professor Sumio Ishihara at GraduateSchool of Science, Tohoku University has indicated that light irradiation causes high-speed “spin transition”, which is the change of spin size in metal-oxides, and makes lumps (the bound state) of spin, through theoretical simulation. The research result has been published online in Physical Review Letters on October 14, 2011. The paper’s title is “Photoinduced change in the spin state of itinerant correlated electron system.”
