Abstract

Single buffer layer of LaMnO₃ (LMO) has been epitaxially grown on biaxially textured Ni and Ni-alloy substrates by sputter deposition. The property characterizations revealed that LMO buffers can serve both as a chemical as well as a structural buffer for YBa₂Cu₃O_7-δ (YBCO) films. Epitaxial YBCO films grown on LMO buffers using pulsed laser deposition (PLD) have self-field critical current densities (J_c) exceeding 1 × 10₆ A/cm² at 77 K. The present results have demonstrated the strong prospect of LMO for the practical development of YBCO coated conductors.
