In-plane magnetic anisotropy of Fe atoms on BiSe(111)
J. Honolka, A. A. Khajetoorians, V. Sessi +11
The robustness of the gapless topological surface state hosted by a 3D topological insulator against perturbations of magnetic origin has been the focus of recent investigations. W…
Electronic and magnetic structure of carbon nanotubes using x-ray absorption and magnetic circular dichroism spectroscopy
Sanjeev Gautama, P. Thakur, S. Augustine +5
Carbon nanotubes are a fraction of the size of transistors used in today's best microchips, as it could reduce power demands and heating in next electronics revolution. Present stu…
BaVS probed by V L edge X-ray absorption spectroscopy
V. Ilakovac, N. B. Brookes, J. Criginski Cezar +10
Polarization dependent vanadium L edge X-ray absorption spectra of BaVS single crystals are measured in the four phases of the compound. The difference between signals with the…
Hole-depletion of ladders in SrCuO induced by correlation effects
V. Ilakovac, C. Gougoussis, M. Calandra +7
The hole distribution in SrCuO is studied by low temperature polarization dependent O K Near-Edge X-ray Absorption Fine Structure measurements and state of the…
Magnetism of cobalt nanoclusters on graphene on iridium
Chi Vo-Van, Stefan Schumacher, Johann Coraux +5
The structure and magnetic properties of Co clusters, comprising from 26 to 2700 atoms, self-organized or not on the graphene/Ir(111) moiré, were studied in situ with the help of s…
High Tc superconductivity in superlattices of insulating oxides
D. Di Castro, M. Salvato, A. Tebano +13
We report the occurrence of superconductivity, with maximum Tc = 40 K, in superlattices (SLs) based on two insulating oxides, namely CaCuO2 and SrTiO3. In these (CaCuO2)n/(SrTiO3)m…
