Combined effect of demagnetizing field and induced magnetic anisotropy on the magnetic properties of manganese-zinc ferrite composites

Popis výsledku v původním jazyce

> This work is devoted to the analysis of factors responsible for the high-frequency shift of the complex permeability (mu) dispersion region in polymer composites of manganese?zinc (MnZn) ferrite, as well as to the increase in their thermomagnetic stability. The magnetic spectra of the ferrite and its composites with polyurethane (MnZn?PU) and polyaniline (MnZn?PANI) are measured in the frequency range from 1 MHz to 3 GHz in a longitudinal magnetization field of up to 700 ?? and in the temperature interval from minus 20 degrees C to plus150 degrees C. The approximation of the magnetic spectra by a model, which takes into account the role of domain wall motion and magnetization rotation, allows one to determine the specific contribution of resonance processes associated with domain wall motion and the natural ferromagnetic resonance to the mu. It is established that, at high frequencies, the mu of the MnZn ferrite is determined solely by magnetization rotation, which occurs in the regi
