Abstract
An oxide magnetic material comprising main constituents including Fe2O3, ZnO, CuO and NiO. Y2O3 of 0.003 to 0.021 wt % and ZrO2 of 0.06 to 0.37 wt % are included in said main constituents with respect to all amounts. It is also preferable that Si of 0.010 to 0.0112 wt % is included in said main constituents with respect to all amounts. Further, it is also preferable that Y2O3 of 0.001 to 0.011 wt %, ZrO2 of 0.031 to 0.194 wt %, and Si of 0.010 to 0.056 wt % are included in said main constituents with respect to all amounts.
