PURPOSE:To obtain a low loss oxide magnetic material ensuring a small loss of electric power even in use at such high-frequency as about 100kHz and capable of being put to practical use. CONSTITUTION:This magnetic material contains, by mol, 50-56% Fe2O3, 30-45% MnO and 5-20% ZnO as principal components and further contains, by weight, 0.03-0.1% CaO, (-)0.05% SiO2, (-)0.4% TiO2 and <=16.98X10<-3>% K as subsidiary components. |
