Polycrystalline samples of Ba2(ZnxFe1−x)2Fe28O46 [(ZnxFe1−x)2−X, 0≤×≤1] X-type hexaferrites were prepared by the ceramic method. Magnetization, magnetic moment, and Curie temperature were investigated. With increasing Zn content the magnetization and magnetic moment increase linearly, but the Curie temperature decreases. A discrepancy between experimental and theoretical values of the magnetic moment, which increases with increasing Zn content, was observed. The effect may be due to the partial occupation of the octahedral sites by the Zn2+ ions and resulting in random spin canting.
