We investigated the properties of magnetic monatomic nanowires deposed on a nonmagnetic substrate by means of ab-initio calculations within the framework of the density-functional theory. The focus was on the magnetic anisotropy (MA) which results from the spin-orbit coupling. We clearly demonstrated that the MA in magnetic atoms was essentially influenced by the nonmagnetic neighborhood, and hence can be tailored by the properties of the substrate.

In series of papers we presented results of our research in the field of high permanent magnets based on RE-TM intermetallic alloys in the form of powders or films (1-4). The influence of various processing parameters on the final magnetic properties of thin magnetic films prepared by PLD and the core-shell nanostructures were studied (3). Based on detailed microstructure study using TEM/EDS we proposed the mechanism of anisotropy in nanocrystalline powders (4); disproportionation kinetics in HDDR processing and nitriding of Sm-Fe alloys in-situ was fallowed by using VSM (5).

One of the most prominent accomplishments for promotion of science and research was issuing of the scientific monograph »Mineral localities of Slovenia«, which is a result of multidisciplinary studies in the fields of geology, stratigraphy and tectonics, geochemistry, crystallography and solid state processes during crystal growth. The book will serve as a basic reference material for university studies in geology, mineralogy, chemistry and nature preservation.

For the first time we have identified the mechanism, which can be used to control the growth of ZnO grains. At the atomic scale we showed that inversion boundaries (IBs) are growth faults that can be used to tailor the microstructure development in ZnO ceramics; this can be employed to tailor the breakdown voltage and tailor the electrical properties of ZnO-based ceramics. This widely opens the pathways for the production of a new generation of low-doped and highly efficient varistor components.

We have developed a new analytical method for accurate measurement of chemical composition of solids at the atomic scale. The method is based on acquisition of EDXS or EELS with concentric electron probes (CEP). In HAADF-STEM imaging we have developed a co-called IMAGE-WARP method for polynomial dewarping geometrically distorted HAADF-STEM images, which was implemented as a new method in measuring thickness and lattice distortions in layered nano-sized heterostructures.
