PROBLEM TO BE SOLVED: To provide low loss oxide magnetic material at a low cost and its manufacturing method by using oxide iron material of low cost which contains a large amount of P2 O5 . SOLUTION: Oxide iron material containing P2 O5 of 0.01-0.1wt.% is used, whose main component consists of Fe2 O3 of 52-54mol%, Mn of 33-39mol%, and ZnO of 0.7-15mol%. As the subcomponent, the following are contained; SiO2 of 0.002-0.01wt.%, CaO of 0.02-0.15wt.%, and Ta2 O3 of 0.005-0.08wt.%. |
