“…1 Since this perovskite is chemically stable, exhibits excellent electrical conductivity, and has a good lattice matching with various functional oxides, it is the material of choice for electrodes, heterojunctions, and multiferroic devices. [2][3][4][5][6][7] One of the most important questions concerning the physics of SrRuO 3 is a significance of correlation effects and how physical properties of the material are impacted by correlated movement of electrons. 8 Due to highly extended nature of 4d orbitals, it is natural to assume that correlation effects in 4d transition metal oxides should be weak.…”

“…Fixing of the ͑110͒ favors an orthorhombic phase, while in bulk BiFeO 3 rhombohedral ͗111͘ type polarizations are stable. Recent work on SrTiO 3 thin films [20][21][22] also show that epitaxial strain has significant effects on the structures of thin films. Similar effects have been observed in lead-based relaxors as well, where the near-surface region or "skin" layers have different structures than that of the bulk.…”

“…Both bulk and films of this material have a metal-insulator transition around 200K. Recent x-ray diffraction measurements on epitaxial films of NdNiO 3 on LaAlO 3 have shown that the out of plane lattice constant exhibits a sudden change at the transition [17]. Further experiments are ongoing to try to determine what makes the two transitions fundamentally different with respect to the clamping effect of the substrate and the relaxation of the overall unit cell dimensions.…”

“…Clearly the overall rise in T C can be quite large. Further detail will be given in a follow up paper [10], that also includes a discussion of the temperature-strain phase diagram which has been theoretically predicted [11].…”
