- Abstract
LaMnO (LMO) cap layers with different surface roughness were prepared on epi-MgO/ion-beam-assisted deposition (IBAD) MgO/solution deposition planarized (SDP) YO/Hastelloy tape. The effects of the surface roughness of LMO on the crystallization, texture and superconducting properties of YBaCuO (YBCO) films were systematically investigated. The crystallization and epitaxial texture of resulting YBCO film are significantly improved with the surface roughness of LMO decreasing from 7.0 to 1.3 nm. High-performance YBCO-coated conductors could be achieved if surface roughness of LMO cap layer is well controlled.
