Abstract :

Nd-substituted Sr hexaferrite (Sr_1-xNd_xFe₁₂O₁₉) plate-like particles were synthesized hydrothermally and then calcined at temperatures ranging from 1100°C to 1250°C 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 1/8 increases the coercivity without causing any significant deterioration in either the saturation magnetization or the remanence.
