Hall Effect and Transverse Conductivities of NbSe₃: Evidence for the Sliding Motion of Charge-Density-Wave

Abstract

The Hall voltage and conductivities perpendicular to the b-axis of NbSe₃ were measured. The former is strongly current-dependent in the non-Ohmic regime, while the transverse conductivities are Ohmic. The results are consistently explained by taking account of the contribution of the sliding charge-density-wave to the conductivity parallel to the b-axis.
