Magnetic properties were studied for magnetoplumbite type ferrites, namely, Z, W or Y type hexagonal ferrites, whose basal planes contain the easy direction of magnetization. Increase in the degree of crystal orientation of these ferrites is known as an effective method to enhance their permeabilities. Accordingly, we have already obtained highly crystal-oriented samples by applying a hot-forging process in air, using normally calcined powders as starting materials. Here, a molten-salt process is adopted to prepare new powders of the ferrites composed of plate-like particles. The degrees of crystal orientation of the hot-forged samples are expected to enhance by replacing the normally calcined powders with these powders.
