Epitaxial LuBa2Cu3O7-δ films were prepared by flash evaporation MOCVD on LaAlO3, SrTiO3, LaSrGaO4 and ZrO2(Y2O3) single crystalline substrates. The highest Tc and jc (77 K, 100 Oe) values were 89 K, 2.7×106 A/cm2 (LaAlO3) and 88 K, 1.5×106 A/cm2 (SrTiO3) respectively. The occurrence of secondary phases inclusions in LuBa2Cu3O7-δ films correlates with the possibility of epitaxial relations with the film matrix or the substrate. |
