摘要：
We report on the resistivity in CeNiSn at temperatures down to 0.035 K and in magnetic fields up to 20 T. The resistivity as a function of temperature T exhibits T-2 dependence with a huge coefficient. Clear Shubnikov-de Haas (SdH) oscillations are observed for the two samples where the electrical current is applied along the b-axis, while possible traces of SdH oscillations are noticed for the other two samples where the current is applied along the a and c axes, respectively.
