Abstract
We report the physical properties of La0.7Sr0.3MnO3 thin films on Sr2IrO4 single crystals. The manganite films are deposited using oxide molecular beam epitaxy on flux-grown (001)-oriented iridate crystals. Temperature-dependent magnetotransport and x-ray magnetic circular dichroism measurements reveal the presence of a ferromagnetic metallic ground state in the films, consistent with films grown on SrTiO3 and La0.3Sr0.7Al0.65Ta0.35O3. A parallel resistance model is used to separate conduction effects within the Sr2IrO4 substrate and the La0.7Sr0.3MnO3 thin films, revealing that the measured resistance maximum does not correspond to the manganite Curie temperature but results from a con(v)olution of properties of the near-insulating substrate and metallic film. The ability to grow and characterize epitaxial perovskites on Sr2IrO4 crystals enables a new route for studying magnetism at oxide interfaces in the presence of strong spin-orbit interactions.
