Experimental demonstration of vortex pancake in high temperature superconductor

Abstract

In order to demonstrate the existence of the vortex pancake in high temperature superconductor experimentally, a configuration in which the current and voltage electrodes lies separately on the top and bottom surface is used. The E-j relation obtained with this electrodes spatial configuration is different from the expected E-j behavior of the stiff vortex line model. Thus, the current results support the existence of the vortex pancake in high temperature superconductor.
