Pure Cu and Mn films exhibit face-centred cubic (fcc) Cu and alpha-Mn phases, respectively. At room temperature the low Mn content films have fcc structure (c-phase). Mn can substitute Cu in the fcc Cu lattice up to 35 at.% Mn. The lattice parameter of fcc Cu–Mn alloy films follows a linear relationship of a0 = aCu + 0.322c(in A), where aCu = 3.615A ˚ is the lattice parameter of Cu and c is the Mn atomic concentration. At high Mn content, above 50 at.% Mn, a homogeneous one-phase structure is observed, possessing the short-range order of a-Mn. The incorporation of Cu into Mn suggests that this structure changes from crystalline a-Mn to disordered structure as the Cu content increases. A narrow two-phase region exists between 35 and 45 at.% Mn. A grain size minimum of 2–3 nm was observed in the 35–65 at.% Mn region.}, year = {2012}, eissn = {1873-2453}, pages = {7226-7231}, orcid-numbers = {Czigány, Zsolt/0000-0001-6410-8801; Radnóczi, György/0000-0002-5056-7625} } @article{MTMT:1962341, title = {Electron Diffraction Based Analysis of Phase Fractions and Texture in Nanocrystalline Thin Films, Part III: Application Examples}, url = {https://m2.mtmt.hu/api/publication/1962341}, author = {Lábár, János and Adamik, Miklós and Barna B., Péter and Czigány, Zsolt and Fogarassy, Zsolt and Horváth, Zsolt Endre and Geszti, Olga and Misják, Fanni and Morgiel, J and Radnóczi, György and Sáfrán, György and Székely, Lajos and Szuts, T}, doi = {10.1017/S1431927611012803}, journal-iso = {MICROSC MICROANAL}, journal = {MICROSCOPY AND MICROANALYSIS}, volume = {18}, unique-id = {1962341}, issn = {1431-9276}, abstract = {In this series of articles, a method is presented that performs (semi) quantitative phase analysis for nanocrystalline transmission electron microscope samples from selected area electron diffraction (SAED) patterns. Volume fractions and degree of fiber texture are determined for the nanocrystalline components. The effect of the amorphous component is minimized by empirical background interpolation. First, the two-dimensional SAED pattern is converted into a one-dimensional distribution similar to X-ray diffraction. Volume fractions of the nanocrystalline components are determined by fitting the spectral components, calculated for the previously identified phases with a priori known structures. These Markers are calculated not only for kinematic conditions, but the Blackwell correction is also applied to take into account dynamic effects for medium thicknesses. Peak shapes and experimental parameters (camera length, etc.) are refined during the fitting iterations. Parameter space is explored with the help of the Downhill-SIMPLEX. The method is implemented in a computer program that runs under the Windows operating system. Part I presented the principles, while part II elaborated current implementation. The present part III demonstrates the usage and efficiency of the computer program by numerous examples. The suggested experimental protocol should be of benefit in experiments aimed at phase analysis using electron diffraction methods.}, keywords = {computer program; quantitative analysis; nanocrystals; texture; thin films; TEM; phase fractions; ring patterns; SAED; electron diffraction}, year = {2012}, eissn = {1435-8115}, pages = {406-420}, orcid-numbers = {Lábár, János/0000-0002-3944-8350; Barna B., Péter/0000-0002-2662-7659; Czigány, Zsolt/0000-0001-6410-8801; Fogarassy, Zsolt/0000-0003-4981-1237; Horváth, Zsolt Endre/0000-0002-4632-0136; Radnóczi, György/0000-0002-5056-7625; Sáfrán, György/0000-0003-3708-3551} } @misc{MTMT:2392877, title = {Formation of TI surface roghness and Au nanoparticles by laser and ion beam process and their size dependet properties}, url = {https://m2.mtmt.hu/api/publication/2392877}, author = {Pető, Gábor and Karacs, Albert and Geszti, Olga and Molnár, Á. and Joób-Fancsaly, Árpád and Frey, Krisztina and Guczi, László}, unique-id = {2392877}, year = {2011}, orcid-numbers = {Joób-Fancsaly, Árpád/0000-0001-7433-0078} } @CONFERENCE{MTMT:1865696, title = {SiO2 supported Ag-Au alloy nanoparticles with high catalytic activity in selective oxidation of glucose}, url = {https://m2.mtmt.hu/api/publication/1865696}, author = {Frey, Krisztina and Benkó, Timea and Geszti, Olga and Guczi, László and Schay, Zoltán}, booktitle = {Proc. of Final workshop of the COST D36 Action}, unique-id = {1865696}, year = {2011}, pages = {39-40} } @CONFERENCE{MTMT:1858964, title = {HRTEM Simulation of Au and Au-Pd Core-Shell Nanoparticles}, url = {https://m2.mtmt.hu/api/publication/1858964}, author = {Kovácsné Kis, Viktória and Geszti, Olga and Süle, Péter and Kovács, Zs. and Sáfrán, György}, booktitle = {ISMANAM – International Symposium of on Metastable, Amorphous and Nanostructured Materials}, doi = {10.13140/RG.2.2.24676.78727}, unique-id = {1858964}, year = {2011}, pages = {214}, orcid-numbers = {Sáfrán, György/0000-0003-3708-3551} }
