Superconductivity in Ti₄O₇ and γ-Ti₃O₅ films.

ABSTRACT: Titanium dioxide is one of the most popular compounds among simple oxides. Except for the fully oxidized titanate, titanium oxides have partially filled d states and their exotic properties have captured attention. Here, we report on the discovery of superconductivity in Ti₄O₇ and γ-Ti₃O₅ in a thin film form. The epitaxial Ti₄O₇ and γ-Ti₃O₅ thin films were grown using pulsed-laser deposition on (LaAlO₃)_0.3-(SrAl_0.5Ta_0.5O₃)_0.7 and α-Al₂O₃ substrates, respectively. The highest superconducting transition temperatures are 3.0 K and 7.1 K for Ti₄O₇ and γ-Ti₃O₅, respectively. The
