中文摘要：

研究了快淬Nd12-xSmxFe84B6（x=0-12）薄带的磁性能。结果表明：快淬速度为30m/s,矫顽力和磁化强度都随Sm含量的增加而减少。剩磁比随Sm含量的增加呈现先降后升再降的趋势。由于Sm2Fe14B的磁晶各向异性低于Nd2Fe14B,随Sm替代量的增加,Nd12-xSmxFe84B6合金的磁晶各向异性逐渐降低,导致矫顽力逐渐减少。

英文摘要：

The magnetic properties of Nd12-xSmxFe84B6 melt-spun ribbons （x=0-12） were investigated. The results show that the coercivity and saturation magnetization both decrease with the increase of Sm content under rapid quenching speed of 30 m/s. The remanence ratio shows the tendency of falling firstly and rising and then falling with the increase of Sm content. Because the magnetocrystaUine anisotropy of Sm2Fe14B is lower than that of Nd2Fe14B ,the magnetocrystalline anisotropy of Nd12-xSmxFe84B6 decreases gradually with the increase of the substitution by Sm,which should be responsible for the decrease of coercivity graduaUy.
