| 英文摘要 | The microstructure and magnetic domain-wall motion of a sintered Sm(Co,Fe,Cu,Zr)(z) permanent magnet with different Cu and Fe contents was investigated by Lorentz transmission electron microscopy. The domain-wall motion under different magnetic fields indicates that most domain walls are strongly attracted by the SmCo5 boundary phases, but some of them are repulsed to the Sm2Co17 cell phase. Differences in Cu and Fe distribution at the SmCo5 cell boundary phase and the SmCo5/Sm2Co17 interface are considered to result in domain-wall behavior, and a larger Cu and a smaller Fe content in the sample make the attractive pinning force stronger and, therefore, coercivity is higher. |
