General Formalism for Magnetic Anisotropy Constants
Daisuke Miura, Ryo Sasaki, Akimasa Sakuma
Direct expressions for the magnetic anisotropy constants are given at a finite temperature from microscopic viewpoints. In the present derivation, it is assumed that the Hamiltonia…
Spin-wave-induced spin torque in Rashba spin-orbit coupling system
Nobuyuki Umetsu, Daisuke Miura, Akimasa Sakuma
We study the effects of Rashba spin-orbit coupling on the spin torque induced by spin waves, which are the plane wave dynamics of magnetization. The spin torque is derived from lin…
Theoretical evaluation on the temperature dependence of magnetic anisotropy constants of Nd2Fe14B - Effects of exchange field and crystal field strength -
Ryo Sasaki, Daisuke Miura, Akimasa Sakuma
To identify the possible mechanism of coercivity (Hc) degradation of Nd-Fe-B sintered magnets, we study the roles of the exchange field acting on the 4f electrons in Nd ions and th…
