Light-induced torque in ferromagnetic metals via orbital angular momentum generated by photon-helicity
Koki Nukui, Satoshi Iihama, Kazuaki Ishibashi +7
We investigated photon-helicity-induced magnetization precession in CoPt alloy thin films. In addition to field-like torque, attributable to magnetic field generation…

First-principles study of exchange stiffness constant of half-metallic Heusler alloys Co2MnZ (Z= Si, Al) at finite temperatures: Spin fluctuation-induced effective half metallicity
Shogo Yamashita, Akimasa Sakuma, Mikihiko Oogane
We performed first-principles calculations at finite temperatures to investigate the temperature dependence of the magnetic properties, such as exchange stiffness constants and Cur…
