Abstract
SnO2 was added to high-permeability MnZn ferrites and MnZn ferrites for high-frequency power supplies. The effects of the SnO2 addition were studied. Sn4+ ions can dissolve into the spinel lattice and form stable Fe2+–Sn4+ pairs and hence can compensate the magneto-crystalline anisotropy constant K1 and improve the initial permeability effectively. The initial permeability of ferrites is also improved as abnormal grain growth caused by ion vacancy is controlled with SnO2 doping. In addition, the SnO2 doping also leads to a decrease in the relative loss factor and an increase in density. The power loss and minimum power loss temperature decrease with SnO2 doping.
