Single 3d transition metal atoms on multi-layer graphene systems: electronic configurations, bonding mechanisms and role of the substrate

Autor: V Sessi, S Stepanow, A N Rudenko, S Krotzky, K Kern, F Hiebel, P Mallet, J-Y Veuillen, O Šipr, J Honolka, N B Brookes

Publikováno v: New Journal of Physics, Vol 16, Iss 6, p 062001 (2014)

The electronic configurations of Fe, Co, Ni and Cu adatoms on graphene and graphite have been studied by x-ray magnetic circular dichroism and charge transfer multiplet theory. A delicate interplay between long-range interactions and local chemical b

Origin of interface magnetism in BiMnO3/SrTiO3 and LaAlO3/SrTiO3 heterostructures

Autor: M, Salluzzo, S, Gariglio, D, Stornaiuolo, V, Sessi, S, Rusponi, C, Piamonteze, G M, De Luca, M, Minola, D, Marré, A, Gadaleta, H, Brune, F, Nolting, N B, Brookes, G, Ghiringhelli

Publikováno v: Physical review letters. 111(8)

Possible ferromagnetism induced in otherwise nonmagnetic materials has been motivating intense research in complex oxide heterostructures. Here we show that a confined magnetism is realized at the interface between SrTiO3 and two insulating polar oxi

Two-dimensional systems, such as ultrathin epitaxial films and superlattices, exhibit magnetic properties distinct from bulk materials. Despite the extensive research on the magnetic properties of metal nano-structures and more recently metal oxide i

In-plane magnetic anisotropy of Fe atoms on Bi2Se3(111)

Autor: J, Honolka, A A, Khajetoorians, V, Sessi, T O, Wehling, S, Stepanow, J-L, Mi, B B, Iversen, T, Schlenk, J, Wiebe, N B, Brookes, A I, Lichtenstein, Ph, Hofmann, K, Kern, R, Wiesendanger

Publikováno v: Physical review letters. 108(25)

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. We present a comprehensive study of the magnetic properties of Fe impur

Thin conductive diamond films as beam intensity monitors for soft x-ray beamlines

Autor: Ken Haenen, V. Sessi, Paulius Pobedinskas, Kurt Kummer, F. Yakhou-Harris, Stoffel D. Janssens, N. B. Brookes, Oliver A. Williams, A. Fondacaro, Jakob Hees

Publikováno v: Review of Scientific Instruments. 84:035105

Quantitative analysis of X-ray absorption and dichroism data requires knowledge of the beamline photon flux during the measurements. We show that thin conductive (B-doped) diamond thin films can be an alternative to the widely used gold meshes for mo
