YBa2Cu3O7-x Superconducting Thin Films Grown on CaNdAlO4(100) Substrates

Abstract

We report the fabrication of high temperature superconducting YBa2Cu3O7-x thin films on CaNdAlO4(100) substrate by pulsed laser deposition. Films have excellent features. X-ray diffraction patterns show that thin films are epitaxial with c-axis orientation normal to the surface of substrate. The four-terminal measurements indicate the zero resistance temperature of 92.1 K, and transition width of 0.7 K, the critical current density of 3 × 106 A/cm2 at 77 K and under zero magnetic field.
