Microscopic Calculation of Spin Torques and Forces
H. Kohno, G. Tatara, J. Shibata +1
Spin torques, that is, effects of conduction electrons on magnetization dynamics, are calculated microscopically in the first order in spatial gradient and time derivative of magne…
Microscopic Calculation of Spin Torques in Disordered Ferromagnets
Hiroshi Kohno, Gen Tatara, Junya Shibata
Effects of conduction electrons on magnetization dynamics, represented by spin torques, are calculated microscopically in the first order in spatial gradient and time derivative of…
Threshold Current of Domain Wall Motion under Extrinsic Pinning, -Term and Non-Adiabaticity
Gen Tatara, Toshihiko Takayama, Hiroshi Kohno +3
Threshold current of domain wall motion under spin-polarized electric current in ferromagnets is theoretically studied based on the equation of motion of a wall in terms of collect…
