Differentiating Dirac from non-Dirac bands in Kagome metal ScV₆Sn₆

The Kagome lattice is an ideal platform to present topological properties within the strong electron correlation regime due to its special geometric structure. The Kagome metal family AV₃Sb₅ (A=K, Cs, Rb) has been discovered recently to host the entanglement of charge density wave (CDW), superconductivity, and topological electronic structure. Here, we measured another Kagome metal ScV₆Sn₆, which also exhibits CDW ordering without superconductivity in the ground state. We conducted the resistance and magnetic torque measurements at base temperature to search the quantum oscillations in order to map the Fermi surface. The Landau Level indexing resolved the trivial and nontrivial Berry phases from different bands. We will compare the observations with the electronic structure modeling to shed light on the “Diracness” of the related bands.
