Abstract :
Manganese-zinc ferrites of relatively high iron content were prepared. The content of ferrous iron was controlled by suitable substitution, thus shifting the second permeability maximum and the minimum of the losses into the range of 60 to 120 °C. These ferrites were found to exhibit high Curie temperature and saturation polarization.
