Determination of Nonlinear Equivalent Parameters of a Ferromagnetic-Film Resonance System in the Case of Excitation of Magnetostatic Waves

摘要

The results of the experimental study on the amplitude- and phase-frequency characteristics of a microstrip-resonator-ferromagnetic-film system with backward magnetostatic volume waves are used to determine the parameters of an equivalent circuit containing two resonance circuits. Dependences of nonlinear equivalent parameters of the system on the power level of the input signal are obtained. Empirical dependences of nonlinear equivalent parameters are also obtained for different intensities of the magnetic field and power levels of the input signal.
