Ferromagnetic resonance in polycrystals
Journal de Physique et le Radium, 1959 The theory of ferromagnetic resonance in polycrystalline material is developed for the two cases in which the anisotropy field is either very large or very small compared with the saturation magnetization. Experimental results obtained with cubic and hexagonal ferrites of large anisotrapy agree reasonably well with the theory.
