Cellular structure regulation and coercivity enhancement induced by La2O3 doping in 2:17 type SmCo magnet

The nanoscal cellular structure and coercivity was effectively regulated by doping La2O3 in Sm(Co0.79Fe0.09Cu0.90Zr0.03)7.68 magnet. The coercivity was gradually enhanced from 20.24 kOe to 24.18 kOe with doping content increasing. The evolution of the microstructure and magnetization reversal behavi...
