PURPOSE:To get an oxide magnetic material where Q in high frequency band area is high and besides the open porosity of a sintered substance is small and is suitable as the core material for a high-frequency low-loss chip coil. CONSTITUTION:This material contains Fe2O3, MgO, CuO, Bi2O3, and NiO at such ratios that the respective containment percentages are 44-49.0mol% for Fe2O3, 2.2-9.3mol% for MgO, 1.0-4.1mol% for CuO, 0.1-1.6mol% for Bi2O3, and the remainder for NiO. |
