Effect of La-Zn Doping on Magnetic Properties of SrFe₁₂O₁₉

Abstract:

La-Zn doped strontium ferrite, Sr_1-xZn_xFe_12(1-x) La_12xO_19, was prepared by chemical co-precipitation method. The samples were characterized by XRD, SEM and VSM and the results reveal that La-Zn ions are dispersed completely into the strontium ferrite lattice at 900°C. The VSM analysis shows that H_cj increases to 240.1 KA/m, almost double the value of the original sample. And the specific saturation magnetization increases from 48.78 A • m²/Kg to 63.11A• m²/Kg.
