Abstract

Due to its low intrinsic damping, Y $_{3}$ Fe $_{5}$ O $_{12}$ 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 $G^{↑↓}$ . $G^{↑↓}$ has been shown to enhance the damping of the ferromagnetic layer. The theory suggested that the effect of $G^{↑↓}$ on gyromagnetic ratio only come from its negligible imaginary part. In this article, we show that the different damping of ferrimagnetic lattices induced by $G^{↑↓}$ can affect the gyromagnetic ratio of Gd-substituted Y $_{3}$ Fe $_{5}$ O $_{12}$ .
