Abstract

Single-crystalline thin films of Sr 2MoO 4 with K 2NiF 4 structure have been epitaxially grown by a pulsed laser deposition on SrTiO 3(1 0 0) and DyScO 3(1 1 0) substrates. Phase-pure and high crystalline quality films were obtained in quite a narrow window of growth condition. The resistivity shows a metallic behavior and the residual resistivity is about two orders of magnitude lower than that of polycrystalline samples. Such single-crystalline Sr 2MoO 4 films are suitable for examining the physical properties and exploring heterostructures with other oxides.
