摘要：

Ba-M hexagonal ferrites with Sb2O3 doping have been prepared in the composition series BaO(Fe2O3)6-x(Sb2O3)x with 0 less-than-or-equal-to x less-than-or-equal-to 0.4. Cold pressed mixture of the starting oxides has been given heat treatment in the temperature range 1100 to 1300-degrees-C for periods extending to 12 h. Sb2O3 doping reduces the values of saturation magnetization and Curie temperature. A cationic distribution scheme with Sb3+ ions occupying the octahedral sites in the S block of the Ba-M hexagonal crystal structure predicts magnetization changes similar to those observed experimentally.
