Figure 4. Frequency dependence of spin-pumping signals in Y3Fe5O12/CoO/Pt.

Figure 4

(a) A pseudo-colour plot of VISHE/Pab as a function of the temperature T and the microwave frequency f for the Y3Fe5O12 (3 μm)/CoO (3 nm)/Pt (10 nm) trilayer film. (b) Temperature (T) dependence of VISHE/Pab at various exciting microwave frequencies. (c) Exciting microwave frequency (f) dependence of VISHE/Pab at various temperatures. We did not show the data for frequencies lower than 4 GHz because the magnetization precession can be modulated due to the three-magnon interaction when f<4 GHz (ref. 40).
