		On the sructure of utrathin FeO flms on Ag(111) Ultrathin transition metal oxide films exhibit unique physical and chemical properties not observed for the corresponding bulk oxides. These properties, originating mainly from the limited thickness and the interaction with the support, make those films similar to other supported 2D materials with bulk counterparts, such as transition metal dichalcogenides. Ultrathin iron oxide (FeO) films, for example, were shown to exhibit unique electronic, catalytic and magnetic properties that depend on the type of the used support. Ag(111) has always been considered a promising substrate for FeO growth, as it has the same surface symmetry, only similar to 5% lattice mismatch, is considered to be weakly-interacting and relatively resistant to oxidation. The reports on the growth and structure of ultrathin FeO films on Ag(111) are scarce and often contradictory to each other. We attempted to shed more light on this system by growing the films using different preparation procedures and studying their structure using scanning tunneling microscopy (STM), low energy electron diffraction (LEED) and X-ray photoelectron spectroscopy (XPS). We observed the formation of a previously unreported Moire superstructure with 45 angstrom periodicity, as well as other reconstructed and reconstruction-free surface species. The experimental results obtained by us and other groups indicate that the structure of FeO films on this particular support critically depends on the films' preparation conditions. We also performed density functional theory (DFT) calculations on the structure and properties of a conceptual reconstruction-free FeO film on Ag(111). The results indicate that such a film, if successfully grown, should exhibit tunable thickness-dependent properties, being substrate-influenced in the monolayer regime and free-standing-FeO-like when in the bilayer form.

		Room temperature magnetism of few-nanometers-thick Fe3O4(111) films on Pt(111) and Ru(0001) studied in ambient conditions Few-nanometers-thick Fe3O4(111) filmswere epitaxially grown on Pt(111) and Ru(0001) single crystal supports by sequential iron deposition and oxidation in an ultra-high vacuum chamber. The growth of well-ordered magnetite films was confirmed by low energy electron diffraction. The films were covered with a protective Au layer and subjected to magnetic and structural studies in ambient conditions. Magnetic hysteresis loops, recorded using magneto-optical Kerr effect apparatus, confirmed magnetic ordering in both films at room temperature. The Kerr measurements indicated in-plane orientation of magnetization, which was supported by the lack of magnetic contrast in magnetic force microscopy images. Atomic force microscopy revealed significant differences in morphology of the films, tentatively attributed to different lattice mismatch with Pt(111) and Ru(0001) single crystal supports.

		Structure of Fe3O4(111) films on Pt(111) and Ru(0001): The role of epitaxial strain at the iron oxide/metal single crystal interface Thin oxide films epitaxially grown on metal single crystal surfaces may exhibit structural properties that differ from the corresponding bulk oxide materials. The structure of the films is often rendered by their thickness, the structure and properties of the substrate and by the nature of the oxide/substrate interface. We prepared thin iron oxide films on Pt(111) and Ru(0001) and studied their structure using STM, LEED and XPS. The structure of FeO(111) - the iron oxide phase that forms at the interface with the metal single crystal - depends on the parameters of the support and is believed to further influence the structure of thicker iron oxide films, such as Fe3O4(111), that are being grown on top of it. In this article we discuss the role of one of the important parameters that may determine this structure - the epitaxial strain at the iron oxide/metal single crystal interface.

		Brillouin spectroscopy and finite element method study of surface acoustic wave propagation in clean and Fe3O4(111) covered Pt(111) and Ru(0001) single crystals Brillouin light scattering was used to study surface acoustic wave propagation in platinum (111) and ruthenium (0001) single crystals, both clean and loaded with a few-nanometre-thick epitaxial magnetite (111) film. The results revealed the influence of the film loading on the velocity of surface acoustic wave propagation in the studied samples. The surface acoustic modes were additionally analysed by finite element method simulations. (C) 2015 Elsevier B.V. All rights reserved.

		Raman spectroscopy indications of the Verwey transition in epitaxial Fe3O4(111) films on Pt(111) and Ru(0001) Temperature-dependent Raman spectroscopy was used for studying few-nanometers-thick epitaxial Fe3O4(111) films grown on Pt(111) and Ru(0001) single crystal supports. The changes in position, intensity and full width at half maximum of the magnetite's A(1g) peak, corresponding to symmetric stretching of oxygen atoms along Fe-O bonds, were monitored in temperatures ranging from 300 to 80 K. The results gave indications of the presence of the Verwey transition in magnetite films on both supports. (C) 2015 Elsevier B.V. All rights reserved.
