Our recent research achievements led by Takumi Matsuo (Ph.D. candidate at Johns Hopkins University) have been published in Nature Communications. This study provides a thorough understanding of the mechanisms behind the magnetic reversal of Mn3Sn induced by an electric current—specifically, the temperature-assisted mechanism and the intrinsic mechanism driven by spin-induced torque—and demonstrates that by controlling these mechanisms through film thickness, switching phenomena on the picosecond scale can be achieved.

The lower path shows magnetization reversal caused by heat generated by the applied current, while the upper path shows magnetization reversal due to an intrinsic mechanism driven by spin-orbit torque.
