Abstract

The Josephson ac effect manifested by both the microwave induced constant voltage steps and a dc voltage shift has been observed in Tl-based high-Tc superconducting bridges. The induced dc voltage (Vdc) is caused by the non-reflecting vortex motion. From the temperature dependence of the Vdc, we inferred three different structures of vortices in this thin film; vortex glass, fluid and unbinding vortex-gas. The nature of the last state is believed to be closely related to the occurrence of Kosterlitz-Thouless transition in a quasi-two dimensional system.
