Abstract

Highly c-axis-oriented SmBa₂Cu₃O_7−x (SmBCO) epitaxial films were deposited on (100)-LaAlO₃ (LAO) single crystal substrates by metal-organic chemical vapor deposition using Sm(dpm)₃, Ba(dmp)₂/Ba(tmod)₂ and Cu(dpm)₂ as precursors. The effect of the precursors’ ratio on the crystalline phases, composition and microstructure of films were investigated. The highly c-axis-oriented SmBCO films with stoichiometry were obtained at the precursors’ molar ratio at Sm: Ba: Cu = 1: 5.12–5.54: 2.16–2.82, with the in-plane epitaxial orientation relationship of SmBCO[100] // LAO[010] and SmBCO[010] // LAO[001].
