Transverse voltage in a quasi-one-dimensional NbSe_3 conductor with a charge density wave in zero magnetic field

摘要

The appearance of an electric field component normal to the transport current has been revealed in NbSe_3 single crystals in the region of phase transitions to the Peierls state. It has been shown that the arising transverse voltage is V_(xy) ~∝ dR_(xx)/dT. This effect is explained by the redistribution of the current caused by the spatial inhomogeneity of the critical temperature of the Peierls transition.
