PROBLEM TO BE SOLVED: To provide a low-loss oxide magnetic material composed of a highly efficient low-loss Ni-Zn ferrite which is stable against thermorunaway, etc. SOLUTION: A low-loss oxide magnetic material contains 48.0-50.0 mol % (excluding 50.0 mol %) Fe2O3, 20.0-32.0 mol % ZnO, 3-7 mol % CuO, and the balance NiO as main ingredients in an Ni-Zn ferrite and 10 wt.% or lower (excluding 0 wt.%) MoO3 as an auxiliary ingredient. |
