This paper analyzes hysteresis losses of minor loops versus temperature in MnZn ferrite core. The study is carried out through an experimental analysis in the temperature range-32°C to +110° C. The most interesting result is a nonmonotonic behavior of losses versus temperature for minor loops defined between magnetic field relatively close around the zero value. Such a result is qualitatively explained on the basis of a competition between exchange energy and magnetic anisotropy. In more detail, the relationships between permeability and exchange energy as well as coercivity and magnetic anisotropy are discussed via recognized models.
