Abstract
The structural and electrical properties of in situ laser deposited thin films of YBa2Cu3O7−x on SrTiO3(110) substrates were studied as a function of deposition temperature. It was found that at low temperatures, grains with the 〈110〉 axis perpendicular to the substrate surface dominated. At higher temperatures, 〈103〉 perpendicular films were obtained. The Jc was found to be extremely anisotropic. For 〈103〉 perpendicular films at 70 K, the Jc’s were found to be 0.85×106 A/cm2 and 5×102 A/cm2 along the substrate 〈100〉 and 〈110〉 directions, respectively.This publication has 21 references indexed in Scilit:
