研究了CeRu2Al10单晶的输运性质。所有输运性质在T0以下都表现出很大的各向异性。沿a轴和c轴的那些显示出相似的行为，但不同于沿b轴的那些。这表明，该系统可以被视为一个二维系统。热导率和温差电势的计算结果可以用T0以下的单重态基态来解释。然而，基态并不简单，而是在自旋能隙内具有某种结构。
We studied the transport properties of CeRu 2 Al 10 single crystals. All the transport properties show largely anisotropic behaviors below T 0 . Those along the a - and c -axes show similar behaviors, but are different from those along the b -axis. This suggests that the system could be viewed as a two-dimensional system. The results of the thermal conductivity and thermoelectric power could be explained by assuming the singlet ground state below T 0 . However, the ground state is not simple but has some kind of structure within a spin gap.
