Abstract: Secondary spin waves effect generated as a result of three-magnon decay processes and threshold-free fusion processes of parametric spin waves on spin pumping in YIG(100)/Pt structures has been studied using the inverse spin Hall effect. It has been shown that the magnitude of the EMF signal, determined by the efficiency of spin pumping from YIG to Pt, reaches the highest values at such a value of the external magnetic field H, at which the generated secondary spin waves most effectively populate the spectrum of anisotropic volume waves characterized by areas with a high density of states.
Keywords: surface magnetostatic waves, three-magnon decay processes, parametric spin waves, secondary spin waves, cubic anisotropy, inverse spin Hall effect
