Abstract

We have prepared magnetic anisotropy polycrystalline hexaferrites Sr_0.95Ca_0.05Fe₁₂O₁₉, whose orientation degrees is up to 100%, and its dielectric loss is lower at 2.3×10^-3, which has not being reported up to date, by standard ceramic techniques during wet pressing and in flowing-oxygen sintering. Such hexaferrites has better millimeter-wave properties. So we make further research on magnetic crystal anisotropy field (Ha) with temperate (T), and make comparison with the magnetism of hexaferrites SrFe₁₂O₁₉.
