Fully textured growth of Y1Ba2Cu3O7−δ films by sputtering on LiNbO3 substrates

Abstract
We present details about the deposition of thin Y1Ba2Cu3O7−δ films on single‐crystal LiNbO3 substrates by planar dc magnetron sputtering. Among other data, results of transition temperature (Tc(R=0) =88 K) and critical current density (jc >2×109 A/m2 at 77 K) plus some details about film‐to‐substrate orientation which is present in all three crystallographic directions are reported.
