Abstract
we have carrierd out comparative investigations of the ''critical'' cu rrent density and the microstructure of several highly textured thin f ilms of YBa2Cu3O7, using Transmission Electron Microscopy. We find tha t the very high current density (7x10(11)(A/m(2)) at H=0 and T=4.2K) c annot be explained by the observed microstructure. A mechanism based o n intrinsic pinning and demagnetization is proposed.
