The role of 2D Vortex fluctuations has been investigated in BSCCO-2223 and YBCO films. Resistance versus temperature and current-voltage characteristics have been discussed in terms of the Ginzburg-Landau Coulomb gas model. It is shown that the analysis is able to extract new interesting information about the interplane coupling (2D-3D crossover) both for BSCCO-2223 and YBCO. Furthermore strong evidence that 2D vortex fluctuations play an important role for BSCCO-2223 is given.

Abstract

Resistance versus temperature and current-voltage characteristics have been discussed in terms of the Ginzburg-Landau Coulomb gas model. It is shown that the analysis is able to extract new interesting information about the interplane coupling (2D-3D crossover) both for BSCCO-2223 and YBCO. Furthermore strong evidence that 2D vortex fluctuations play an important role for BSCCO-2223 is given.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
