  Abstract The time-differential perturbed angular correlations technique (TDPAC) has been employed for measuring the parameters of hyperfine interactions in earlier known RAl 3 compounds, synthesized at high pressure (8 GPa) and high temperature, where R = La, Ce, Sm, Gd, Tb, Dy, Ho, Er, Yb and Lu. The 111 Cd( 111 In) radioactive atom was used as a probe nucleus. The X-ray method has revealed that with

  摘要 时差微扰角相关技术 (TDPAC) 已被用于测量在高压 (8 GPa) 和高温下合成的早期已知 RAl 3 化合物中超精细相互作用的参数，其中 R = La、Ce、Sm、 Gd、Tb、Dy、Ho、Er、Yb 和 Lu。111 Cd( 111 In) 放射性原子被用作探针核。X射线法表明，随着稀土元素R原子序数的增加，得到的RAl 3 高压相分别结晶成正交、六方和立方结构。已经发现，在含有R=La、Ce、Sm和Gd的化合物中，观察到与早期已知结构类型的偏差和新结构类型的形成，这与所述化合物的化学计量组成的变化有关。

  Abstract We present the results of an investigation of the ground state in CeAl 3 via substitution of Ga, Si, Ge and Sn for Al in Ce(Al 1− x M x ) 3 . Anomalies in the low temperature specific heat, magnetic susceptibility and electrical resistance reveal an antiferromagnetic ground state for all samples. The data of CeAl 3 fit easily to the results of our doping series. We conclude that the anomalies

  摘要 我们展示了通过用 Ga、Si、Ge 和 Sn 代替 Ce(Al 1− x M x ) 3 中的 Al 来研究 CeAl 3 中基态的结果。低温比热、磁化率和电阻的异常表明所有样品都处于反铁磁基态。CeAl 3 的数据很容易符合我们掺杂系列的结果。我们得出结论，CeAl 3 低温数据的异常是由于反铁磁性造成的。这种化合物中可能存在反铁磁相关性或什至有序的磁态。这些相关性也有助于索末菲系数 γ 的高值。评估哪些参数对CeAl 3 及其掺杂衍生物的磁性能起决定性作用。

  Temperature dependence of the thermal expansion coefficient alpha and the electrical resistivity rho of Ce1-xLaxAl3 compounds has been measured for various lanthanum concentrations x. It is found that the temperature dependence of alpha and rho is influenced largely by substitution of lanthanum. The results are briefly discussed in connection with the Kondo effect and crystalline electric field splitting of the 4f level of the Ce3+ ion.

  The electrical resistivity rho(T) of the heavy fermion compound CeAl3 has been measured under high pressure up to 1.5 GPa in order to clarify the volume dependence of the electronic state in the heavy fermion. It is found that the temperature showing a maximum in the rho(T) curve increases with increasing pressure. Compressibility was also measured using the X-ray diffraction technique at high pressure. On the basis of the data, a quantitative analysis of the volume dependent energy scale is examined using a simple theoretical model.
