FLUXOID MOTION AND RESISTIVE TRANSITION IN HIGH CRITICAL TEMPERATURE SUPERCONDUCTORS.

Author(s) : MATSUSHITA T., NI B.

Type of article: Article

Summary

THE RESISTIVE BEHAVIOUR IN HIGH TEMPERATURE SUPERCONDUCTORS, AS WELL AS IN LOW TEMPERATURE SUPERCONDUCTORS, CAN BE EXPLAINED BY THE MECHANISM OF FLUX FLOW. THE ANISOTROPIC RESISTIVE TRANSITION, WITH RESPECT TO FIELD DIRECTION, CAN BE MOSTLY EXPLAINED BY THE ANISOTROPY IN THE UPPER CRITICAL FIELD. THE KNEE IN THE RESISTANCE-TEMPERATURE CURVE CORRESPONDS TO THE IRREVERSIBILITY TEMPERATURE AT WHICH THE CRITICAL CURRENT DENSITY GOES TO ZERO UNDER A GIVEN MAGNETIC FIELD. THE TEMPERATURE AND MAGNETIC FIELD DEPENDENCES OF THE FLOW RESISTIVITY IN HIGH TEMPERATURE SUPERCONDUCTORS ARE DIFFERENT FROM THOSE IN LOW TEMPERATURE ONES.
