Abstract

The high temperature superconducting YBCO films were deposited on the SrTiO$_3$(100) single crystals to find out the proper deposition conditions of YBCO on biaxially-textured metal substrates. Different sets of the substrate temperature, oxygen partial pressure and laser fluence were used to investigate the effect of deposition conditions on the superconducting properties. The new apparatuses for measuring critical temperature (Tc) and critical current (Ic) were designed and manufactured, which were used to obtain Tc's and Ic's of the deposited films. The accuracy of the new apparatus was confirmed by comparing the results with those from SQUID magnetometer. The results on the YBCO films deposited on single crystal substrates which will be used to get the optimum deposition conditions of YBCO films in the coated conductor, are summarized in this report.
