Effect of spin Hall magnetoresistance on spin pumping measurements in insulating magnet/metal systems

Iguchi, Ryo*; Sato, Koji*; Hirobe, Daichi*; Daimon, Shunsuke*; Saito, Eiji

We investigate a dc rectification effect of magnetization dynamics based on spin Hall magnetoresistance (SMR) in an insulating magnet/metal system on spin pumping measurements. We theoretically find that the rectification effect by SMR has different in-plane magnetization angle dependence from that of the inverse spin Hall effect on the spin pumping. The negligible contribution from the rectification effect is experimentally confirmed in a cavity measurement.
