The influence of the microstructure parameters on the magnetic losses in soft magnetic ferrites for television engineering
Source abstract
Abstract
Abstract The effect of the chemical composition and microstructural parameters on the frequency dependence of the electromagnetic properties of the Mn–Zn ferrites in strong fields has been studied. We show that the frequency dependence of the electrical conductivity in the ferrites originates from highly ohmic thin layers of high dielectric permeability at the grain boundaries. The eddy current loss is proportional to the frequency and inversely proportional to the magnetic permeability of the ferrites.
