Single crystal growth of Ce-T-Al(T=transition metals) and development of physical property measurements by GM cryocooler

Ce金属间化合物的磁性可以用Doniach模型来描述，该模型描述了Kondo和RKKY相互作用之间的竞争。尽管CeU_2Al_(10)&Gt；处于近藤效应占主导地位的非磁性基态区域，但通过对CeU_2Al_(10)&Gt；及其相关化合物的多个极端条件下的宏观和微观测量，我们认为这种相变不能用Doniach模型来描述。

Magnetic properties of Ce intermetallic compounds have been considered to be understood by Doniach model which describes the competition between Kondo and RKKY interaction. In spite of CeRu_2Al_<10> is located in the non-magnetic ground state regime in which Kondo effect is dominant, a phase transition appears at a temperature as high as 27 K. From the macroscopic and microscopic measurements under multiple extreme condition using high quality single crystals of CeRu_2Al_<10> and the related compounds, we have proposed that this phase transition cannot be described by Doniach model.
