摘 要：The microwave properties have been studied on Polycrystalline hexaferrite BaZn(GeMn)*** X-ray diffrection has shown that the W-type hexaferrites BaZn(GeMn)xFeO can not be formed at x≥*** anisotropy field of hexaferrite BaZn(GeMn)FeO measured at room temperature is 7.90×10A/*** exchange interaction constants and the contributions to magnetocrystalline anisotropy for various sublattices in BaZn(GeMn)FeO have been calculated based on the molecular field theory and ***’s single ion anisotropy *** results show that the sublattices 12k and 2d have stronger contribution to anisotropy.
