We perform first-principles molecular dynamics of liquid oxygen in which the magnetic structure evolves according to a generalized density-functional scheme allowing for noncollinear spin configurations. We investigate both structural correlations between ...
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 ...
We have investigated the orbital magnetization of tunable two-dimensional electron-systems (2DES) in GaAs/AIGaAs-heterostructures in the magnetic quantum limit using a high-sensitive superconducting susceptometer. In particular we have studied the magnetiz ...
Carbon-13 solid-state NMR is used to determine, via the temperature dependence of paramagnetic shifts, the spin ladder of magnetic levels and the related spin exchange parameters in 4Fe-4S clusters. This study has been carried out between 180 and 330 ...
The isotropic magnetic moment of a free atom is shown to develop giant magnetic anisotropy energy due to symmetry reduction at an atomically ordered surface. Single cobalt atoms deposited onto platinum ( 111) are found to have a magnetic anisotropy energy ...
A rapid algorithm for tomographic inversion is presented that allows post-discharge reconstruction of the soft x-ray (SXR) emissivity evolution in the Tokamak a configuration variable (TCV). Simultaneously, it determines the centre of gravity of the emissi ...
MnPS3 is a quasi-2D S = 5/2 antiferromagnet on a honeycomb lattice. Using an energy integrating neutron scattering technique, we have measured the structure factor S(k) of the instantaneous magnetic fluctuations. The temperature dependence of the correlati ...
We have performed time-resolved pump–probe measurements on arrays of 1 μ m -wide Fe wires and on a 50 μ m -wide Fe stripe. A photoconductive switch was used as a source of fast-risetime magnetic field pulses. The magnetization dynamics were detected by the ...
We have used electrically detected magnetic resonance (EDMR) to study the spin dependent processes on the operation of diodes based on poly(2-metoxy-5-(2'-etil-hexiloxy)-1,4-phenylene vinylene) (MEH-PPV) and on tris-8-hydroxyquinoline-aluminum (Alq3
We have carried out an ab initio molecular dynamics simulation of liquid oxygen, a molecular fluid in which the individual 02 units carry a molecular magnetic moment. In addition to the atomic and electronic structures, our simulation describes the evoluti ...
