Abstract

We fabricated epitaxial thin films of oxygen-vacant Sr 2MgMoO6-δ using pulsed laser deposition. The films showed low resistivity of the order of 10-2 Ω cm at 300 K. X-ray diffraction analyses revealed that Mg and Mo ions in the Sr 2MgMoO6-δ films were considerably disordered, compared to those in bulk Sr2MgMoO6-δ. The proportion of oxygen vacancies estimated through hard x-ray photoemission measurements was as large as 0.37, and correlated well with the Mg/Mo ordering.
