摘要

报道了YCo4B化合物在145k时的自旋取向,其磁矩随温度的降低从c轴向基面旋转。初步的晶体场计算表明,YCo4B中6i位的负各向异性较大,是低温下化合物基面各向异性的主要原因。这种对各向异性的负贡献与2c位上Co离子的正贡献之间的竞争可能是观察到的自旋重取向的原因。[忽略俄语文本]。

Anomaly in the Magnetic Properties of the YCo4B Compound
Spin reorientation observed in the YCo4B compound at 145 K in which the magnetic moment rotates from the c-axis to the basal plane on decreasing temperature is reported. A preliminary crystal field calculation reveals that the negative anisotropy of 6i site in YCo4B is large and responsible for the basal plane anisotropy of the compound at low temperature. The competition between this negative contribution to anisotropy and the positive one from the Co ion on the 2c site may be the reason of the observed spin reorientation. [Russian Text Ignored].
