Abstract
PURPOSE:To obtain novel spinel type ferrite by obtaining a composite spinel type ferrite represented by Li2/3Ge1/3Fe2O4. CONSTITUTION:Li2CO3 and GeO2, Fe2O3 are mixed at a molar ratio of 1:1:3, and the mixture is temporarily baked. The mixture is then baked at 1,200-1,450 deg.C to produce a composite spinel type ferrite represented by Li2/3Ge1/3Fe2O4. This ferrite has much higher Curie point than the room temperature (538 deg.C) and relatively large saturation magnetization, and can accordingly expect the utilization to a magnetic head or the like as a soft ferrite. In this manner, novel spinel type ferrite can be obtained.
