Temperature impact on the spectra of the spin-wave resonance in two-layer magnetic films

Abstract

A sharp difference has been revealed in the behavior of the temperature dependences of the spectra of the spin-wave resonance of two-layer films with different parameters of the pinning layers. The calculations have shown that the effect of the disappearance and subsequent appearance of spin-wave modes in the specific temperature ranges was connected with the decrease in the degree of pinning because of the convergence of the fields of uniform resonance in the layers of excitation and pinning of spin fluctuations.
