摘要 Y(Co 1 - x Fe x ) 3 化合物的各向异性能量已确定在 4.2 和 250 K 之间。各向异性能量的浓度依赖性在这个伪二元级数中表现异常。随着铁含量的增加,各向异性能量增加到 x = 0.25,然后减小,在 x = 0.45 附近改变符号并在富铁侧达到平坦的最小值。通过考虑 3d 站点的铁和钴的不同占用因子,可以根据单个站点各向异性模型对这种异常进行令人满意的解释。

Magnetic measurements were performed on Y(FexAl1 - x)(3) compounds in the temperature range 5 to 800 K and external fields up to 7 T. Compounds with x > 0.8 are ferromagnets. For x < 0.8 short-range order and freezing effects of magnetic clusters originating from replacement of Fe by Al are evidenced. The mean magnetic moments of iron clusters as well as their number are estimated. Above the Curie points, the thermal variations of magnetic susceptibilities obey Curie-Weiss type behavior. The mean effective magnetic moments per iron atom are only weakly dependent on composition.
