    Modelling of the oxidation of Suspended Silicon Nanowires

    The oxidation of suspended Si nanowires is studied under wet and dry conditions. The nanowire characteristics are extracted from Electron Microscopy images. In parallel, the Deal and Grove model is extended to...

    Size Dependent Enhancement of Spin and Orbital Magnetism in CoRh Nanoparticles

    The magnetism of CoRh nanoparticles (NPs) is investigated experimentally and theoretically. NPs of about 2 nm diameter have been synthesized by decomposition of organometallic precursors in mild conditions of ...

    Oxidation of Si nanocrystals fabricated by ultra-low energy ion implantation in thin SiO2 layers

    The effect of annealing in diluted oxygen on the structural characteristics of thin silicon dioxide layers with embedded Si nanocrystals fabricated by ultra-low energy ion implantation (1 keV) is reported. The...

    Anomalously high charge/orbital ordering temperature in Bi0.5Sr0.5MnO3

    Neutron/synchrotron diffraction data and magnetic measurements provide direct evidence of charge/orbital ordering at anomalously high temperatures in Bi0.5Sr0.5MnO3, as well as in other (Bi,Sr)MnO3 manganites. We...

    Charge modulation and orientational variants in Bi1/3Ca2/3MnO3

    We present a neutron/synchrotron diffraction study of the orbital/charge ordering in Bi1/3Ca2/3MnO3. The compound presents a high degree of orthorhombicity, which has permitted us to identify different modulation...
