de Haas-van Alphen Untersuchungen nichtmagnetischer Borkarbidsupraleiter
Im Rahmen dieser Doktorarbeit werden de Haas-van Alphen-Untersuchungen an den nichtmagnetischen Borkarbidsupraleitern LuNi2B2C und YNi2B2C präsentiert. Aus den Quantenoszillationen in der normalleitenden Phase in Kombination mit Bandstrukturrechnungen konnten Informationen über die verzweigte …

Quantum oscillation studies in the unconventional superconductor YFe₂Ge₂ and in the Dirac semimetal candidates NbXSb (X = Ge/Si)
… It also shows an anomalous power law temperature dependence of the electrical resistivity (ρ = ρ0 + AT³⁄²) which indicates Fermi liquid breakdown, possibly connected to its vicinity to a quantum critical point. The materials NbXSb (X = Ge/Si) have been theoretically predicted via initial density …

Quantum oscillations in Dirac semimetals
… materials. Among the many candidates, the tellurides NbTe₄, TaPtTe₅ and TaNiTe₅ appear to provide a promising platform for the study of such topological properties. To probe their band structure and its corresponding Fermi surface, quantum oscillations have proven very useful as they provide a …

Fermi Surfaces and Where to Find Them: Quantum Oscillations in Kondo Insulators and High-Temperature Superconductors
… at the Fermi level. It is these electrons that underpin most physical properties of metals, and have made quantum oscillations, the experimental manifestation of the Fermi surface, a hallmark signature of metals. In this thesis we have studied systems that are distinctly non-Fermi liquid, and …

Effect of high pressure on the Fermi surfaces of zinc and aluminum
… the Fermi surfaces of zinc and aluminum has been determined by using the field-modulation technique to detect de Haasvan Alphen oscillations and by using solid helium as a pressure medium. The primary result obtained in the study of zinc was that the (0001) cross section of the needle portion of …

Quantenphasenübergänge in den Schwere-Fermionen-Systemen Yb(Rh_{1-x}M_x)_2Si_2 und CePd_{1-x}Rh_x
… stellt ein wichtiges Themengebiet im Bereich der Festkörperphysik dar. Das Verhalten von Schwere-Fermionen-Systemen wird durch die starken Korrelationen der magnetischen Momente der ungepaarten Spins der f-Elektronen bestimmt. Experimentell zugängliche Messgrößen sind dadurch bei tiefen …
