中文摘要：

研究了快淬Nd12-xYxFe84B6薄带的磁性能。结果表明：快淬薄带主要由R2Fe14B相组成,且矫顽力、剩磁和饱和磁化强度都随Y含量的增加而减少。矫顽力的减少主要是由于Y元素的替换导致各向异性降低所引起的。

英文摘要：

The magnetic properties of Nd12-xYxFe84B6 melt-spun ribbons were studied. The results show that the melt-spun ribbons mainly consist of R2Fe14B phase. The coercivity, remanence and saturation magnetization of the ribbons decrease with the increase of Y content. The decrease of coereivity is mainly attributed to the decrease of anisotropy due to the substitution, Nd for Y.
