YBa₂Cu₃O_7-x Superconducting Thin Films Grown on CaNdA1O₄(100) Substrates

We report the fabrication of high temperature superconducting YBa₂Cu₃O_7-x thin films on CaNdA1O₄(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 su bstrate. The four-terminal measurements indicate the zero resistance temperature of 92.1 K, and transition width of 0.7K, the critical current density of 3 x 10⁶ A/cm² at 77K and under zero magnetic field.
