Influence of Sn-substitution on temperature dependence and magnetic disaccommodation of manganese–zinc ferrites

In this paper, the effects of Sn-substitution on temperature dependence and magnetic disaccommodation of manganese–zinc ferrites were investigated. Toroidal cores were prepared by the conventional ceramic process and sintered at 1360 °C for 4 h in atmosphere controlled by using the equation for equilibrium oxygen partial pressure. The experimental results show that the substitution of Sn4+ in manganese–zinc ferrites can influence the thermal stability and disaccommodation remarkably. Secondly, the temperature dependence of the initial permeability μi and disaccommodation of Sn-substitution manganese–zinc ferrites have an internal relationship. The experimental results are explained and compared with those of Ti-substitution manganese–zinc ferrite.
