susceptibility and specific heat of intermetallic R 3 Ni (R=heavy rare earth or Y) are presented. The comparative analysis allowed us to determine origin of magnetic anomalies as well as to define their temperatures more precisely. It is shown that strong short-range magnetic ordering remains above T N . The effect of spin freezing have been found in almost all investigated R 3 Ni. The specific splitting of
摘要 介绍了金属间化合物R 3 Ni(R=重稀土或Y)的初始磁化率和比热的测量和分析结果。比较分析使我们能够确定磁异常的起源并更准确地定义它们的温度。结果表明,强短程磁有序保持在 TN 之上。在几乎所有研究的 R 3 Ni 中都发现了自旋冷冻的影响。地面多重峰的特定分裂导致一些R 3 Ni 化合物中相当不寻常的磁熵行为。
