Superconductors have a poor thermoelectric figure of merit (zT) on their own due to a symmetric density of states (DOS). However, in the presence of an external magnetic field, the DOS of the up and down spin states becomes asymmetric separately. A spin filtering material can then be added to detect only one of the two spin states. This project builds on previous efforts to measure thermoelectric effects in S-F hybrids. By improving experimental design over previous efforts, we will test the predicted thermoelectric efficiency and further the understanding of thermal transport in S-F systems.born digitalmasters thesesengCopyright of the original work is retained by the author.cryogenicssuperconductivitythermoelectricitythermometryText2024-06-25
