Magnetic anisotropy of paramagnetic and ferromagnetically ordered state of single crystal BaVSe3

Helmuth Berger, László Forró, Ana Akrap

Anisotropic magnetism of single crystal BaVSe3 was Studied for the first time by the combination of the susceptibility and torque methods. As reported previously for polycrystalline sample, BaVSe3 undergoes ferromagnetic ordering below 43 K. Well above fer ...

Transport properties of cluster-assembled magnetic nanostructures

Giulia Di Domenicantonio

The aim of this thesis is to get a deeper understanding of magnetic properties of small clusters when they are embedded in a host material. The study was motivated by the observation of the very peculiar properties that clusters present in the gas phase or ...

Separation, detection and quantification of biomolecules in lab-on-a-chip systems

Frédéric Lacharme

Since the introduction of the of Micro Total Analysis Systems concept in 1990, important progress in microfluidic analytical systems has been realized. In many cases, microfluidic systems have shown improved analytical performances over classical methods, ...

Magnetism induced by single-atom defects in nanographites

Lothar Helm, Oleg Yazyev

We study from first principles the magnetism in graphene induced by single carbon atom defects. For two types of defects considered in our study, the hydrogen chemisorption defect and the vacancy defect, the magnetism due to the defect-induced extended sta ...

Three-dimensionality of field-induced magnetism in a high-temperature superconductor

Henrik Moodysson Rønnow

Many physical properties of high-temperature superconductors are two-dimensional phenomena derived from their square-planar CuO2 building blocks. This is especially true of the magnetism from the copper ions. As mobile charge carriers enter the CuO2 layers ...
