Decoherence effects in nonequilibrium transport through mesoscopic systems
… a quantum wire which is coupled to a ferromagnetic spin chain is investigated using a calculation within the Keldysh Green's function formalism. The electrons in the wire are coupled to spin waves, the so-called magnons, in the spin chain. The self-energy contribution which is due to this …

Magnetic Properties of Molecular and Nanoscale Magnets
… in this fifield. Studying structural and magnetic properties of nano- and molecular magnets and the interplay between these properties reveals new interesting effects and suggests ways to control and optimize the respective material. The main task of this thesis is investigating the …

Voltage Controlled Non-Volatile Spin State and Conductance Switching of a Molecular Thin Film Heterostructure
… a boundary on the scale of new micro and nano magnetoelectronic devices. This necessitates a push into the limits of harnessable natural phenomena to facilitate a post-Moore’s era of design. Requirements for thermodynamic stability at room temperature, fast (Ghz) switching, and low energy cost …

Synthesis, molecular and solid state structures, and magnetic properties of sandwich lanthanide phthalocyanines lacking C-H bonds
… as (F_{64}Pc)_2MH, M = Tb, Dy, Lu, Y. Single molecular magnetic (SMM) behavior in the (F_{64}Pc)_2TbH and (F_{64}Pc)_2DyH complexes was confirmed through slowed relaxation response of their magnetization in an applied time varying magnetic field during alternating current (AC) magnetic testing …

Quantum transport through single molecules
The field of molecular electronics experienced an enormous boost in both experiment and theory in the last few years. Addressing a single molecule is not only of technological interest, also fundamental physical questions arise: Are single molecules the ultimate step in the miniaturization of …

Lanthanide-based single-molecule magnets: A rational design by chemical intuition
… on the observation of single-molecule magnet (SMM) behaviour in a lanthanide-based complex (Dy1). Experimental techniques were combined with theoretical tools to investigate the dynamics of magnetic properties of the Dy1 and compared with the theoretical results for Dy2 to gain insight …
