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 ferrite is known as an effective method to enhance their permeabilities. Hence, a hot-forging process in air was adopted to align the basal planes of the crystallites of the ferrites perpendicular to the hot-forging axis. The degrees of crystal orientation of the hot-forged samples were determined by XRD according to the Lotgerings' definition. It was found that the permeabilities and the degrees of the crystal orientation of the hot-forged samples increased with increasing hot-forging temperature.
