摘要:

研究了CeRu_2Al_(10)单晶的输运性质。所有输运性质在T_0以下均表现出各向异性。沿着a轴和c轴的那些显示出类似的行为,但与沿着b轴的那些不同。这表明该系统可以被看作是一个二维系统。热导率和热电势的计算结果可以通过假设T_0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。

英文摘要:

We studied the transport properties of CeRu_2Al_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.
