Abstract

© (2015) Trans Tech Publications, Switzerland.We investigate Anomalous Hall effect in nonmagnetic metal/ferromagnetic insulator bilayer with rotating magnetization of the magnetic insulator. Spin-orbit interaction of Rashba type takes place near metal/insulator interface. Magnetization of the ferromagnetic insulator rotates with some frequency w by microwave radiation under ferromagnetic resonance condition. This rotation together with spin-orbit interaction in non-magnetic metal layer induced Hall current along the interface. The Hall current appears under zero bias in the system. The dependence of Hall current on the exchange splitting, the magnetization rotation frequency and the barrier height is calculated. We analyze various contributions in Hall current and discuss the limit of small frequencies.
