  vortex
The vortex-like excitations detected by Nernst signals in high-Tc superconductors
      
Experimental demonstration of vortex pancake in high temperature superconductor
      
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.
