Quantum size effects in metallic clusters and multivalent molecularmaterials

Ziel



Research objectives and content
The main objective of this project is to perform a detailed study of the quantum size effects which appear when the physical size of a metallic cluster (containing from a few atoms up to a few thousands) becomes comparable to the wavelength of an electron at the Fermi level. At very low temperatures (<1 K), the magnetic response and the specific heat of clusters becomes markedly different to the 'bulk' metallic behaviour. We intend to study this new type of magnetism in different samples in the presence of an applied field by means of several experimental techniques. The multivalent metal cluster molecules have lower nuclearity, which allows us to calculate complete spin-density mappings. Therefore, we will be able to distinguish whether the magnetic moments are or not delocalised over the molecule. Finally, we will measure the magnetic relaxation of some metallic clusters which are very good candidates to show magnetic quantum tunnelling.I Training
content (objective, benefit and expected impact)
The applicant will get into contact with the new, rapidly expanding field of cluster science. Besides getting a deep education in experimental physics at very low temperature, he will benefit from the interdisciplinary character of this project: chemistry and physics, experiment and theory.
