The review of magnetodynamic resonances in ferrite resonators and their mm-wave band applications was given. Ferrite resonator eigenexcitations classification has been presented. The analytical theory for modes resonant frequencies calculations is stated and a number of prototype electronically tunable mm-wave devices, utilizing the “above” and “below FMR” magnetodynamic resonances, including isolator,...
Effect of magneto-dielectric modes frequency splitting in disc ferrite resonators was considered. Comparison of magnetic field frequency tuning due to mode splitting and ferromagnetic resonance was given. This effect has a fundamental importance since it takes place in both microwave and optical range.
The paper presents a novel method of approximation the magnetizing curve of self-excited induction generators. The main feature of this method is the presence of an additional non-linear region of approximated dependence that is designed to connect the two linear regions corresponding to unsaturated and saturated states of the magnetic system, without the gaps of the function which describes the dependence...
In this paper we consider the system of two ferromagnets semi-infinite media with interface in which spatial inversion symmetry is broken. We obtain the boundary conditions for interface of this model materials. The possibility of nonlinear spin wave formation at transmission of a spin wave through the boundary of two ferromagnets with spatial inversion broken symmetry was shown.
