Abstract
The magnetic properties and frequency spectra were studied in magnetic composites with the MnZn powder filler in polymer matrix. The frequency response of permeability, power loss and reactive power per frequency components were measured and compared with the computed data. For this purpose the model taking into account particle morphology in the selected frequency spectrum was proposed. The frequency responses of permeability components have the adequate frequency dependencies of powers per frequency for the sinusoidal waveform of applied magnetic field.
