Ferromagnetic resonance in polycrystalline ferrites is considered in the framework of the independent-grain model. It is shown that the ferromagnetic resonance absorption line can be obtained analytically from its moments. When a limited number of mo

The method of transition probabilities is used to calculate the line width of ferromagnetic resonance in a medium with an inhomogeneous saturation magnetization. It is shown that in addition to linear (with respect to the Fourier components of the fu

A law is obtained for the approach to saturation with respect to magnetization for anisotropic magnetic materials with inhomogeneous saturation magnetization. In the calculation, the spin-wave formalism is used. The effect of an inhomogeneous exchang

From the viewpoint of the spin-wave approach to the theory of ferromagnetic resonance, the first four moments of the absorption line are calculated in this paper. It is shown that in addition to the magnetic dipole-dipole interaction, the inhomogeneo

The magnetic susceptibility of magnetized ferrites is described by the tensor of second rank $$\overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\leftrightarrow}$}} {\chi } $$ at microwave frequencies. The tensor nature of the susceptibility is det

The width of the ferromagnetic-resonance absorption line and the resonance field in polycrystalline nickel aluminate ferrites were measured as functions of the uniaxial compression. Over a large part of the elastic-stress range studied the experiment

The accuracy of the calculation of the effect of magnetocrystalline anisotropy and of elastic stress anisotropies on the ferromagnetic resonance frequency is investigated by introducing effective demagnetization factors. Relationships are found to de
