Abstract

Experimental and theoretical investigations of the magnetic resonance of “strip” films were conducted. In magnetic fields below the saturation field, when “strip” films possess a periodic domain structure, a multimode character of the absorption spectrum was discovered. The spectrum of spin oscillation taking into account exchange and magnetic dipole interaction was computed. Comparison of the computed results with the experimental data permits the identification of the observed peaks as bulk and surface modes of a spin wave resonance.
