Revealing the anomalous Hall like behavior of Kagome ScV₆Sn₆

Compounds with Kagome lattice structure are known to exhibit nontrivial topology in electronic band structures, leading to several versatile quantum phenomena. One of them is the anomalous Hall like behavior in ScV₆Sn₆, a non-magnetic charge density wave (CDW) compound. The measured value Hall conductivity is of the order of 10⁴ Ω^-1cm^-1, which is fully entangled with the CDW phase. With the help of external and internal pressures, we disentangled the anomalous Hall behavior from the CDW phase, where the CDW phase exhibited significant changes while the anomalous Hall behavior remained unchanged.
