Kinetic Magnetoelectric Effect in Chiral Helimagnets Influenced by Spin-Transfer Torque
摘要
Abstract—
The influence of the spin-transfer torque effect on the nonequilibrium magnetization of conduction electrons in chiral helimagnets, induced by the electric current flowing through the helimagnet, has been investigated. It has been established that the rotation of the magnetization spiral of the helimagnet, caused by the transfer of spin moment from conduction electrons when an electric current flows along the spiral axis, leads to a decrease in the magnitude of the longitudinal (relative to the spiral axis) component of the nonequilibrium magnetization of conduction electrons, which corresponds to the weakening of the kinetic magnetoelectric effect.
