| Abstract: | The influences of the Sm 3+ substitution on structure and magnetic properties of M-type barium ferrites were investigated by XRD,VSM and TEM It is found that partial substitution of Sm 3+ for Ba 2+ appears to slow down the particle growth at high temperature Sm 3+ substitution can result in an increase in the intrinsic coercivity without causing deterioration in the specific saturation magnetization. |

| Keywords: | specific saturation magnetization coercivity ferrite microstructure |
