Fermi surface of Kagome metal ScV₆Sn₆ using high field torque magnetometry

Kagome materials have recently garnered enormous interest due to their exhibition of multiple electronic orders, such as charge density wave (CDW), non-trivial topology, and superconductivity. This work presents the electronic properties of ScV₆Sn₆, a member of the 116-family Kagome compounds, utilizing de Haas-van Alphen (dHvA) oscillations and density functional theory (DFT) calculations. The torque signal, with applied fields up to 43 T, exhibits clear dHvA oscillations with six major frequencies. We computed the electronic band structure and Fermi surface using DFT in both the pristine and CDW phases. Comparison of DFT results with dHvA oscillation frequencies, as well as Lifshitz-Kosevich analyses for determining the effective mass of charge carriers, will be discussed.
