Giant Resistivity Anomaly on the Superconducting Transition in TaSe₃

Abstract

A giant resistivity which depended on the current density, J, was observed within the superconducting transition region of TaSe₃ by measuring the dc resistivity at extremely low J. It is suggested that the giant resistivity has close relations with the superconducting phase itself rather than other phases such as charge-density-waves or spin-density-waves.
