Investigations of nonlocal transport and current noise in mesoscopic normal metal-superconductor hybrid structures
… coherence length. At such distances coherent nonlocal subgap transport takes place. It involves Cooper pair splitting among other theoretically predicted transport processes. In this dissertation we investigate signatures of coherence in nonlocal transport. We focus on current correlation …

Quantum transport in gapped graphene
This thesis focuses on investigating local and nonlocal transport properties in hexagonal boron nitride (hBN)/graphene superlattice Hall bars and graphene Hall bars proximity coupled to the ferrimagnetic insulator yttrium iron garnet ($\text{Y}_{3}\text{Fe}_{5}\text{O}_{12}$ or YIG). The first part …

Magnon Transport in Insulating Magnetic Thin Films
… enables long-distance spin-based information transport with low dissipation. MAFO (MgAl0.5Fe1.5O4) is a spinel ferrite that has been recently stabilized in epitaxial thin-film form and has a substantial in-plane four-fold magnetic anisotropy. Employing nonlocal transport measurements, we …

Investigations of Crossed Andreev Reflection in Hybrid Superconductor-Ferromagnet Structures
… one ferromagnetic wire into the superconductor, nonlocal transport processes involving the second ferromagnetic wire are predicted to take place. We measure a negative nonlocal voltage in the antiparallel magnetization alignment of the ferromagnetic wires, which is the theoretically predicted …

Probing proximity-induced superconductivity in Nb- Bi2Se3 bilayers with low-temperature transport and Josephson interferometry
… of niobium and bismuth selenide. Low temperature transport measurements demonstrate the presence of proximity-induced superconductivity in the topological insulator thin film. Non-local measurements show a surprising nonlocal signal at low bias that is odd in the bias on both contacts. Sharp high …
