Study of the narrow band noise at low temperatures in K_<0.30> MoO_3

本文用电阻测量的方法研究了层状过渡金属二硫族化合物2 H-Tas_2的超导电性转变。我们观察到一个对电流高度敏感的电阻测量。此外，在1.4和4.2 K下分别清楚地观察到电流依赖电阻。这种电流依赖性是第一次报道这种材料。讨论了样品中超导转变温度分布的物理起源。

I have investigated the superconductivity transition in a layered transition-metal dichalcogenide 2H-Tas_2 by means of measuring electrical resistance down to 10 mK. We observed one which is highly sensitive to the current for the measurement of the electrical resistance. In addition the current-dependent- electrical resistance is clearly observed at 1.4 and 4.2 K respectively. This current-dependency is for the first time reported on this material. The physical origin is discussed in terms of the distribution of the superconductivity transition temperature within the specimen.
