Magnetocrystalline anisotropy energy of Co and Fe adatoms on the (111) surfaces of Pd and Rh
Harald Brune, Stefano Rusponi, Pietro Gambardella, Markus Etzkorn, Anne Lehnert, Géraud Moulas
We performed a combined theoretical and experimental investigation of the orbital magnetism and magnetocrystalline anisotropy of isolated Co and Fe adatoms on Pd(111) and Rh(111). Theoretical calculations of the spin and orbital moments are based on ab ini ...
2010Spin dynamics in the S=1/2 antiferromagnetic chain compounds delta-(EDT-TTF-CONMe2)(2)X (X=AsF6, Br): A multifrequency electron spin resonance study
We present a multifrequency electron spin resonance study in the range of 4-420 GHz of the quasi-one-dimensional, nondimerized, quarter-filled Mott insulators, delta-(EDT-TTF-CONMe2)(2)X (X=AsF6, Br). In the high-temperature orthorhombic phase above T simi ...
2010Supramolecular control of the magnetic anisotropy in two-dimensional high-spin Fe arrays at a metal interface
Klaus Kern, Harald Brune, Magalí Alejandra Lingenfelder, Pietro Gambardella, Sebastian Stepanow, Sylvain Clair, Alexandre Dmitriev
Magnetic atoms at surfaces are a rich model system for solid-state magnetic bits exhibiting either classical(1,2) or quantum(3,4) behaviour. Individual atoms, however, are difficult to arrange in regular patterns(1-5). Moreover, their magnetic properties a ...
Nature Publishing Group2009Increase in the Curie temperature and magnetic anisotropy in FePd/Pt-iron oxide core-shell nanoparticles
Partially oxidized fcc FePd and FePt nanoparticles with mean diameters of 5 and 3 nm, respectively, were synthesized by a reverse micelle polyol process. In situ measurements of magnetic and structural properties during annealing showed a large increase in ...
2009Magnetism of individual adatoms and of epitaxial monolayers
This thesis reports on the magnetism of low coordinated Fe and Co atoms in different chemical and electronic environments. The objective of this research was to contribute to the fundamental understanding of the magnetic properties, such as magneto-crystal ...
EPFL2009Fermi Surface and Order Parameter Driven Vortex Lattice Structure Transitions in Twin-Free YBa2Cu3O7
We report on small-angle neutron scattering studies of the intrinsic vortex lattice (VL) structure in detwinned YBa2Cu3O7 at 2 K, and in fields up to 10.8 T. Because of the suppressed pinning to twin-domain boundaries, a new distorted hexagonal VL structur ...
20093D Imaging of the Fermi Surface by Thermal Diffuse Scattering
We use thermal diffuse scattering of x rays to visualize the lens-shaped portions of the Fermi surface in metallic zinc. Our interpretation of the nature of the observed scattered intensity anomalies is supported by the incorporation of inelastic x-ray sca ...
2009Magnetic and resonance properties of the two-dimensional S=1 compound Ni-5(TeO3)(4)Cl-2 with frustrated geometry
The magnetic and magnetoresonance properties of a new single-crystal compound Ni-5(TeO3)(4)Cl-2 are studied. Measurements of the magnetization and magnetic susceptibility of the crystal in a wide temperature range (5-300 K) make it possible to conclude tha ...
2008Growth and magnetism of 2D bimetallic nanostructures
This thesis addresses the growth and magnetic characterization of 2D bimetallic nanostructures deposited by atomic beam epitaxy (ABE) on Pt(111). These structures possess both tunable high perpendicular magnetic anisotropy (PMA) and magnetic moment. These ...
EPFL2008In situ manipulation of magnetic anisotropy in magnetite thin films
We show that the ferromagnetic anisotropy of a thin crystalline Fe3O4 film can be manipulated in situ via the application of tunable stress. The stress is exerted by a piezoelectric actuator, onto which the Fe3O4 film is cemented. The strain in the sample ...
