“A new way of synthesis and characterization of superconducting oxyfluoride Sr2Cu(O,F)4+\delta”. Ardashnikova EI, Lubarsky SV, Denisenko DI, Shpanchenko RV, Antipov EV, Van Tendeloo G, Physica: C : superconductivity 253, 259 (1995)
Abstract: Superconducting Cu mixed oxyfluoride, Sr,Cu(O, F)(4+delta), was Obtained via fluorination of Sr2CuO3 by XeF2 in the 100-250 degrees C temperature range in a closed Ni container. The prepared samples exhibited a lower T-c in comparison with earlier reported values. Different samples in the Sr-Cu-O-F system were prepared by a solid-state reaction at 220-400 degrees C, but no formation of the oxyfluoride was detected even with an addition of xenon difluoride. These data allow one to draw conclusions on the metastability of the oxyfluoride under the conditions used, Electron microscopy and X-ray powder diffraction studies revealed large amounts of badly crystallized SrF2; this could be a reason for the small superconducting volume fraction as well as for the inhomogeneous distribution of the anions.

“The study of a crater forming on the surface of a Ti target submitted to multipulse excimer laser irradiation under low pressure N2”. Teodorescu VS, Mihailescu IN, Gyorgy E, Luches A, Martino M, Nistor LC, van Landuyt J, Hermann J, Journal of modern optics 43, 1773 (1996). http://doi.org/10.1080/095003496154815
Abstract: A Ti target was submitted to laser ablation in low ambient pressure N-2. Electron microscopy examination of the cross-section of the crater zone forming on the Ti target, and XPS analyses, indicate that there is a small effect on the nitridation processes taking place on and in the vicinity of the target. The studies show a zone influenced by the multipulse laser treatment extending beneath the crater down to a depth of the same order of magnitude as the crater depth (i.e. similar to 10 mu m). In this zone, TiN could be identified as being present only in traces, while the whole zone exhibited a layer structure with differences in morphology and mechanical wear.

“Structural defects and epitaxial rotation of C60 and C70 (111) films on GeS(001)”. Bernaerts D, Van Tendeloo G, Amelinckx S, Hevesi K, Gensterblum G, Yu LM, Pireaux JJ, Grey F, Bohr J, Journal of applied physics 80, 3310 (1996). http://doi.org/10.1063/1.363241
Abstract: A transmission electron microscopy study of epitaxial C-60 and C-70 films grown on a GeS (001) surface is presented. The relationship between the orientation of the substrate and the films and structural defects in the films, such as grain boundaries, unknown in bulk C-60 and C-70 crystals, are studied. Small misalignments of the overlayers with respect to the orientation of the substrate, so-called epitaxial rotations, exist mainly in C-70 films, but also sporadically in the C-60 overlayers. A simple symmetry model, previously used to predict the rotation of hexagonal overlayers on hexagonal substrates, is numerically tested and applied to the present situation. Some qualitative conclusions concerning the substrate-film interaction are deduced. (C) 1996 American Institute of Physics.
