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 ...
Coordination assemblies formed by metal(II) dithiocarbamates M-II(R(2)dtc)2 (M = Zn, Cd, Hg, Mn, and Fe; R = Me, Et, iPr, nPr, and nBu) and nitrogen-containing ligands (L = DABCO, DMP, and HMTA) are shown to be sterically well consistent with the spherical ...
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 ...
A miniature susceptometer has been developed that is small enough to fit inside clamp type pressure cells. The design and performances of the device are described, as well as examples of measurements possibly allowed. The susceptometer is comprised of 3 co ...
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 ...
The authors measured the elec. field induced linear dichroism for a wide range of sizes of CdSe nanocrystals. Large ground-state dipole moments were obsd., esp. for the smallest crystals. In these, the authors found a very large anisotropy of the absorptio ...
A semi-empirical potential for ferromagnetic bcc iron that also models the co-linear magnetic moment of each atom, has been applied to clusters and surfaces. Surface energies of low index facets, surface relaxation and magnetic moment are calculated and co ...
This thesis is concerned with supramolecular architectures assembled at metal surfaces. The investigations pursued two objectives. On the one hand, the focus was placed on the fabrication of low-dimensional surface-supported network structures by applying ...
The electronic structure of isolated bis(phthalocyaninato) terbium(ill) molecules, a novel single-molecular-magnet (SMM), supported on the Cu(111) surface has been characterized by density functional theory and scanning tunneling spectroscopy. These studie ...
Individual Mn impurities deposited on Ge(100), Ge(111), and GaAs(110) substrates present magnetic moments significantly larger compared to the average Mn magnetization in bulklike Ga1-xMnxAs and MnxGe1-x dilute magnetic semiconductors. The Mn magnetic mome ...
