Nd-substituted Sr hexaferrite (Sr1-xNdxFe12O19) plate-like particles were synthesized hydrothermally and then Calcined at temperatures ranging from 1100 degreesC to 1250 degreesC for 2 h in air. The effects of the Nd-Sr ratio and the calcination temperature on the phase stability and magnetic properties were investigated. Nd substitution up to a Nd-Sr ratio of M increases the coercivity without causing any significant deterioration in either the saturation magnetization or the remanence.
