Magnetic anisotropy of Fe and Co ultrathin films deposited on Rh(111) and Pt(111) substrates: An experimental and first-principles investigation

Harald Brune, Stefano Rusponi, Pietro Gambardella, Markus Etzkorn, Anne Lehnert, Géraud Moulas

We report on a combined experimental and theoretical investigation of the magnetic anisotropy of Fe and Co ultrathin layers on strongly polarizable metal substrates. Monolayer (ML) films of Co and Fe on Rh(111) have been investigated in situ by x-ray magne ...

Differential geometry: a natural tool for describing symmetry operations

Gervais Chapuis, Kurt Schenk, Philippe Kocian

Differential geometry provides a useful mathematical framework for describing the fundamental concepts in crystallography. The notions of point and associated vector spaces correspond to those of manifold and tangent space at a given point. A space-group o ...

Inducibility of Drug-metabolizing Enzymes by Xenobiotics in Mice with Liver-specific Knockout of Ctnnb1

Massimiliano Schwarz

Basal as well as xenobiotic-induced expression of the main enzymes from phase I and phase II of drug metabolism is confined to the perivenous areas of the mammalian liver lobule. Whereas signal transduction pathways that govern xenobiotic-induced expressio ...

Orientation selection in dendritic evolution

Michel Rappaz

Computational and experimental demonstration of dendritic crystal growth direction and the morphologic diversity of the resulting dendritic structures are discussed. The primary dendrite growth directions can vary continuously between different crystallogr ...

Non-Cytotoxic, Bifunctional EuIII and TbIII Luminescent Macrocyclic Complexes for Luminescence Resonant Energy- Transfer Experiments

Jean-Claude Bünzli, Anne-Sophie Chauvin, Caroline Vandevyver

A new macrocyclic ligand,

L^3

, has been synthesised, based on the cyclen framework grafted with three phenacyl light-harvesting groups and a C5-alkyl chain bearing a carboxylic acid function as a potential linker for biological material. Acidity constant ...

Groupoid of orientational variants

Cyril Cayron

Daughter crystals in orientation relationship with a parent crystal are called variants. They can be created by a structural phase transition (Landau or reconstructive), by twinning or by precipitation. Internal and external classes of transformations defi ...

Structure and magnetism of atomically thin Fe layers on flat and vicinal Pt surfaces

Klaus Kern, Harald Brune, Stefano Rusponi, Pietro Gambardella, Violetta Sessi

Ultrathin Fe films on Pt substrates have been investigated under ultrahigh vacuum conditions by scanning tunneling microscopy, low energy electron diffraction, magneto-optical Kerr effect, x-ray magnetic circular dichroism measurements, and Kerr microscopy ...

Investigation of hexagonal and cubic GaN by high-resolution electron energy-loss spectroscopy and density functional theory

Cécile Hébert

High-resolution electron energy-loss spectroscopy in a transmission electron microscope is a very powerful method for the study of electronic structure of materials. The fine structure of Ga L2,3 and N ionization edges in c-GaN and h-GaN was studied using ...

Propriétés magnétiques de nanostructures de cobalt adsorbées

Nicolas Weiss

This thesis reports results on magnetic properties of supported cobalt nanostructures. The nanostructures were grown on single crystal metal surface by Molecular Beam Epitaxy in an Ultra High Vacuum chamber. Our experimental setup is based on two in situ m ...

The remarkable difference between surface and step atoms in the magnetic anisotropy of two-dimensional nanostructures

Harald Brune, Stefano Rusponi, Philipp Buluschek, Nicolas Weiss, Laurent Claude

The original magnetic properties of nanometre-sized particles are due to the distinct contributions of volume, surface and step atoms. To disentangle these contributions is an ongoing challenge of materials science. Here we introduce a method enabling the ...
