Ni3TeO6 - a collinear antiferromagnet with ferromagnetic honeycomb planes
I. Živković, K. Prša, O. Zaharko +1
We report a comprehensive study of magnetic properties of Ni3TeO6. The system crystallizes in a noncentrosymmetric rhombohedral lattice, space group R3. There are three differently…
Study of diffuse scattering under hydrostatic pressure in PbMg1/3Nb2/3O3
G -M Rotaru, B Padmanabhan, S N Gvasaliya +5
We report measurements of the evolution of the diffuse scattering in a single crystal PbMg1/3Nb2/3O3 as a function of hydrostatic pressure. Upon applying pressure the diffuse scatt…
Dynamical response and confinement of the electrons at the LaAlO3/SrTiO3 interface
A. Dubroka, M. Roessle, K. W. Kim +10
With infrared ellipsometry and transport measurements we investigated the electrons at the interface between LaAlO3 and SrTiO3. We obtained a sheet carrier density of Ns~5-9x 10E13…
Li diffusion in LiCoO probed by muon-spin spectroscopy
Jun Sugiyama, Kazuhiko Mukai, Yutaka Ikedo +3
The diffusion coefficient of Li ions () in the battery material LiCoO has been investigated by muon-spin relaxation (SR). Based on the experiments in z…
Band structure engineering of epitaxial graphene on SiC by molecular doping
Camilla Coletti, Christian Riedl, Dong Su Lee +5
Epitaxial graphene on SiC(0001) suffers from strong intrinsic n-type doping. We demonstrate that the excess negative charge can be fully compensated by non-covalently functionalizi…
Graphene on Ru(0001): A corrugated and chiral structure
D. Martoccia, M. Bjoerck, C. M. Schlepuetz +5
We present a structural analysis of the graphene/Ru(0001) system obtained by surface x-ray diffraction. The data were fit using Fourier-series expanded displacement fields from an…
