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…

Heat-conserving three-temperature model for ultrafast demagnetization of 3d ferromagnets
M. Pankratova, I. P. Miranda, D. Thonig +6
We study the ultrafast magnetization dynamics of bcc Fe and fcc Co using the recently suggested heat-conserving three-temperature model (HC3TM), together with atomistic spin- and l…
