摘要：

The excitation spectrum in an [Fe/Cr](n) multilayer structure with noncollinear magnetic ordering was studied by the ferromagnetic resonance (FMR) method in the frequency interval 9.5-37 GHz at room temperature. Besides an acoustic branch, several additional modes were observed under parallel excitation of resonance. The FMR spectrum was calculated analytically in a biquadratic exchange model, neglecting in-plane anisotropy, for an infinite number of layers in the structure and numerically for a finite number of layers contained in real samples. It was shown that the observed modes correspond to excitation of standing spin waves with wave vectors perpendicular to the film plane. (C) 1998 American Institute of Physics.
