PURPOSE:To provide an oxide magnetic material which has such various advantages that the mechanical strength of the material can be improved, the inductance variation caused by the sintering temperature can be reduced, the quality of an element can be improved when the material is used for the element, and can be sintered at a low temperature. CONSTITUTION:The chemical composition of the title magnetic material is expressed by a(Ni(1-x.Cux)O.bZnO.cFe2O3 (where, a+b+c=100, 0.15<=x<=0.70, 0<=b<=37, and 35<=c<=49.5). The magnetic material is manufactured by power metallurgy by using moldable powder prepared so that the mixing ratio of particles having diameters of >5mum in the moldable powder can be controlled to <=5vol.% and the material can have the above-mentioned chemical composition. |
