Inelastic light scattering in low-dimensional spin systems
… work diverse results obtained from a number of low-dimensional quantum spin systems using Raman spectroscopy have been presented. The main motivation of this thesis is to hunt for new types of elementary excitations which may be present in low-dimensional spin systems with exotic spin topology. …

Electronic structure of strongly correlated low-dimensional spin ½ systems: cuprates and vanadates
… The model visualizes the interplay of the spin-orbit coupling and crystal field splitting. In the fourth chapter we calculated the electronic spectrum of the single Zn impurity in CuO2 plane considered as a vacancy in Cu 3d states. The analytic solution for the states of different symmetry …

Strukturelle und magnetische Eigenschaften der Cu-Divanadate sowie verwandter, niedrigdimensionaler Verbindungen
… magnetic Cu2+ ions (S=1/2) forms different one dimensional chains and two dimensional networks. Thus, the research was motivated by the search of new low-dimensional spin systems and the research of the influence of different Cu-topology or Cu-O-coordination on the magnetic behaviour. The Cu …
