Effects of epitaxial strain on the growth mechanism of YBa2Cu3O7-x thin films in [YBa2Cu3O7-x / PrBa2Cu3O7-x] superlattices
M. Varela, W. Grogger, D. Arias +6
We report on the growth mechanism of YBa2Cu3O7-x (YBCO). Our study is based on the analysis of ultrathin, YBa2Cu3O7-x layers in c-axis oriented YBa2Cu3O7-x / PrBa2Cu3O7-x superlatt…

Direct Correlation between Tc and CuO2 Bilayer Spacing in YBa2Cu3O7-x
M. Varela, D Arias, Z. Sefrioui +4
We report the effects of epitaxial strain and deoxygenation on high quality [YBa2Cu3O7-x (YBCO)_N / PrBa2Cu3O7 (PBCO)_5] (1000 A thick) superlattices, with 1 <= N <= 12 unit cells.…

Superconductivity depression in ultrathin YBa2Cu3O7-x layers in La0.7Ca0.3MnO3 /YBa2Cu3O7-x superlattices
Z. Sefrioui, M. Varela, V. Pena +7
We report on the depression of the superconducting critical temperature of ultra thin YBa2Cu3O7 (YBCO) layers, when their thickness is reduced in presence of La0.7Ca0.3MnO3 (LCMO)…
