Abstract
Due to its low intrinsic damping, YFeO and its substituted variations are often used for ferromagnetic layer at spin pumping experiment. Spin pumping is an interfacial spin current generation in the interface of ferromagnet and non-magnetic metal, governed by spin mixing conductance parameter . has been shown to enhance the damping of the ferromagnetic layer. The theory suggested that the effect of on gyromagnetic ratio only come from its negligible imaginary part. In this article, we show that the different damping of ferrimagnetic lattices induced by can affect the gyromagnetic ratio of Gd-substituted YFeO.
