英文摘要: Spin pumping occurred under nonlinear spin dynamic has been studied in Pt(17 nm)/Y3Fe5O12(YIG 66 nm) heterostructure. By using high power excitation, the precession angle (theta(c)) of YIG can reach a value as high as 22 degrees, and distinct nonlinear dynamic effects such as foldover ferromagnetic resonance spectra and nonlinear damping have been witnessed. The linear relation between the dc component of spin current and sin (2)theta(c) has been tested from linear to nonlinear spin dynamics regimes. Our main finding is that spin mixing conductance is a robust parameter that is independent on the amplitude and damping of the dynamic system, at least in our experiment conditions.
