Optical Investigations of Symmetry Breaking in the CDW State of ScV<sub>6</sub>Sn<sub>6</sub>
POSTER
Abstract
The rich electronic structure of Kagome metals can give rise to complex emergent phenomena, including charge density waves (CDWs) and time-reversal symmetry breaking (TRSB). ScV6Sn6, the only known compound from the vast hexagonal HfFe6Ge6 - type “166” family to exhibit a CDW phase transition, has emerged as a promising platform for studying these phenomena, with enhanced tunability compared to the largely studied AV3Sb5. Recent studies have shown evidence for TRSB in the CDW phase of ScV6Sn6, much like that observed in AV3Sb5. We perform polar Kerr effect measurements on ScV6Sn6 crystals to test for potential TRSB within the CDW state, along with polarization rotation and electrical transport measurements to further investigate symmetry breaking related to the CDW phase.
