| 英文摘要 | The nanoscal cellular structure and coercivity was effectively regulated by doping La2O3 in Sm(Co-0.79-Fe0.09Cu0.90Zr0.03)(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 behavior were investigated. It was found that short-range Th2Zn17 type 2:17R microtwins structure appeared in the vicinity of (La, Sm)(2)O-3 phase after solution treatment in addition to well-ordered Th2Ni17 type 2:17H phase. After aging treatment, the cellular structure nearby the (La, Sm)(2)O-3 phase tend to grow into larger size, while the other cellular structure remain the same size with that in magnet without doping. More importantly, higher Cu content and lower Fe content was observed in the cell boundary phase nearby the oxide than that away from the oxide. The movement of domain wall under applied magnetic field indicated that the pinning field nearby the (La, Sm)(2)O-3 phase was strengthened, which led to the increase of coercivity.
