| 摘要 | We have systemically studied structure and magnetic properties of nanocomposite magnets Nd8-xSmxFe88B4 (x = 0-2.5) prepared by mechanical milling and subsequent heat-treatment. The remanence increases monotonically with Sm substitution for Nd. The value of the maximum energy product exhibits a peak at x = 0.4. The extension of the exchange coupling length is induced by a decrease of the anisotropy of the magnetic-hard phase. This results in that more magnetically soft grains participate well the exchange coupling, improving the magnetic properties of the nanocomposite magnets. Compared with Y substitution for Nd, the Sm substitution for Nd in the Nd12Fe14B/alpha-Fe nanocomposite magnets has stronger effect on decreasing the magnetic anisotropy, thus it has stronger effect on increasing the exchange coupling length.
