Abstract

We examined the physical properties of the quasi-one-dimensional superconductor TaPdTe in the normal state by detailed measurements of susceptibility, in-plane anisotropic resistivity, magnetoresistance, Hall resistivity, and Seebeck coefficient. The large Wilson ratio, as inferred from normal-state susceptibility, indicates strong electron-electron interaction. The Hall and Seebeck coefficients show not only significant temperature-dependent behavior, indicating the multiband effect, but also an obvious anomaly around T   =  40 K. Analyses of both the Hall resistivity and thermopower using a two-band model indicate that the electrons dominate the electrical transport at low temperatures. Our results imply that it is the quantum fluctuations of the charge order taking place in the temperature range 30-50 K that may result in the abnormal normal-state properties of TaPdTe.

摘要

我们通过详细测量磁化率、面内各向异性电阻率、磁阻、霍尔电阻率和塞贝克系数,研究了准一维超导体TaPdTe在正常态下的物理性质。从正常态磁化率推断出的大威尔逊比率表明存在强电子-电子相互作用。霍尔系数和塞贝克系数不仅表现出显著的温度依赖性行为,表明多带效应,而且在T = 40 K左右出现明显异常。使用双带模型对霍尔电阻率和热功率进行分析表明,在低温下电子主导电输运。我们的结果表明,可能是在30 - 50 K温度范围内发生的电荷序量子涨落导致了TaPdTe正常态性质的异常。
