PROBLEM TO BE SOLVED: To provide a low loss oxide magnetic material having a high amplitute permeability. SOLUTION: A low loss oxide magnetic material contains a main component of ferrous oxide (Fe2 O3 ) of 52 to 54mol%, manganese oxide of 33 to 37mol%, the balance of zinc oxide (ZnO), and the auxilliary component of silicon dioxide (SiO2 ) of 0.001 to 0.008wt.% and calcium oxide (CaO) of 0.02 to 0.10wt.%. Besides, tantalum oxide (Ta2 O4 ) of 0 to 0.6wt.% (containing no O) or niobium oxide (Nb2 O4 ) (containing no O) are contained, and also Ta2 O5 and Nb2 O5 of 0 to 0.06wt.% (containing no O) in total are contained. |
