Nonlinear response of magnetization obeying inertial dynamics to superimposed dc and ac fields and dynamic magnetic hysteresis

AIP Advances
The nonlinear ac stationary responses of magnetization and the dynamic magnetic hysteresis of ferromagnetic particles with uniaxial anisotropy acted on by both external dc and ac magnetic fields are evaluated by employing the inertial Landau–Lifshitz ...

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.
