Abstract

High quality YBa₂Cu₃0_7-δ thin films have been fabricated by pulsed Nd:YAG laser deposition using an unusual ’off-axis’ target-substrate geometry. In this geometry one can eliminate the deposition of laser ‘droplets.’ Our films are free of particles and have smooth surfaces. The critical temperature (T_c) of these films is in the range of 87–90 K, which is as high as that of ‘on-axis’ deposited films. From the x-ray rocking curve measurement and the magnetization measurement, no significant differences were found between the ‘on-axis’ and ‘off-axis’ laser deposited films.
