HIGH-QUALITY C-AXIS ORIENTED SUPERCONDUCTING ND1+XBA2-XCU3O7-D THIN-FILMS DEPOSITED BY THE LASER-ABLATION METHOD

High-quality single phase Nd1+xBa2-xCu3O7-d thin films have been fabricated on SrTiO3 substrates by the laser ablation method. The resistivity of the deposited films are usually lower than that of the YBCO film. The Tc(onset) and Tc(R=0) in the optimized thin films are as high as 91 and 88 K, respectively. The crystallinity of our films are higher than the best YBCO films ever reported. The rocking curve FWHM of the (005) peaks in our thin films is typically 0.05°, which is superior to the best reported YBCO films.© 1995 American Institute of Physics.
