Abstract

Magnetic properties were studied for Hexagonal ferrites, namely, Z, W and 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 crystaloriented samples by applying a hot-forging process, on the plate-like ferrite particles obtained by the molten-salt process. Here, we applied a rotational horizontal magnetic field to these particles in a die during a wet molding process to align the plates of the particles vertical to the pressing direction. After then, the pressed compacts were hot-pressed in a furnace to obtain highly crystal-oriented samples. The degrees of crystal orientation of these samples are expected to be comparable with those obtained by the hot-forging process using the same molten-salt powders above mentioned.
