PROBLEM TO BE SOLVED: To provide a low-loss oxide magnetic material which is reduced in loss in a wide frequency range of from zero to 500 kHz. SOLUTION: The main component composition of magnetic material contains 52.5 to 53.5 mol% Fe2O3, 35.0 to 45.0 mol% MnO, and residual % ZnO as main components and 0.005 to 0.05 wt.% SiO2, 0.01 to 0.1 wt.% CaO, 0.005 to 0.1 wt.% Nb2O5, 0.01 to 0.5 wt.% TiO2, and 5.0 wt.% or below Ga2O3 as additives. |
