Abstract

Summary form only given. Mn-Zn and Ni-Zn ferrite samples with different doping levels and sintering temperatures have different microstructures. The spectral analysis of the time rate magnetic flux density proves that at high frequency the wall motions are damped and the spin rotation mechanism leads the magnetization process. In each case the microstructure is correlated with the values of the spectral coefficients.
