Abstract

Sr₂RuO₄ is the only known layered perovskite that is free of copper, yet superconducting. Its low metallic resistivity and excellent lattice match with YBa₂Cu₃O_7-δ make it an attractive candidate for use as conductive electrodes to YBa₂Cu₃O_7-δ-based superconducting devices or as a normal metal in YBa₂Cu₃O_7-δ-based SNS junctions. Single-domain a-axis oriented epitaxial films of Sr₂RuO₄ have been grown in situ by pulsed laser deposition on (1 0 0) LaSrGaO₄ substrates. Single-domain c-axis oriented Sr₂RuO₄ films have been grown on (1 0 0) LaAlO₃, (1 1 0) NdGaO₃, and (1 0 0) SrTiO₃ substrates. Heterostructures containing YBa₂Cu₃O_7-δ have also been grown. Resistivity versus temperature measurements reveal that the as-grown Sr₂RuO₄ films are metallic, but not superconducting.
