The Z type magnetoplumbite ferrite with the composition of 2CoO.3Ba0.5Sr0.5O.10.8Fe2O3 was reported to reveal enhanced dispersion frequency. This paper aims to prepare the highly crystal oriented ferrite, by using a hot-forging technique. The hot-forged samples revealed the orientation degree of more than 90 percent and their permeabilities ranged from 30 to 40. Especially, magnetic losses of the samples hot-forged in an oxygen atmosphere were highly low. The maximum μQ product at 300 MHz reached 600, which was three times of the value of the crystal-oriented sample prepared in the Philips Laboratory.
