Abstract
AbstractThe boundary problem is solved for an isotropic homogeneous infinite insulator film with spins pinned asymmetrically by a uniaxial surface anisotropy. An arbitrarily oriented external magnetic field is assumed. Formally a simple condition for the values of the resonant wave‐vector k1 is obtained. The analytical expressions for the standing spin‐wave resonance (SSWR) mode linewidths and intensities are derived and discussed. The second part of the paper is devoted to the SSWR in thin metallic films with thicknesses 2d ≪ δ (the skin depth). The influence of conductivity on the mode positions, linewidths, and intensities is investigated analytically with the help of the spin‐wave approximation.
