Abstract: The shape of the hysteresis loop of MnZn ferrites depends on
temperature. By increasing the temperature, the squareness of the loop
increases. Consequently, the magnetic properties change the power losses and
the performances of the ferrites. In this paper, a comparison is made between
the calculated hysteresis loops in Jiles-Atherton model and the experimental
loops. The influence of temperature and of the microstructure (size of the
grains, pores and segregation) on the model's parameters is discussed.
