Pressure tuning of the anomalous Hall effect in the kagome superconductor CsV3Sb5
文献摘要:
Controlling the anomalous Hall effect (AHE) inspires potential applications of quantum materials in the next genera-tion of electronics.The recently discovered quasi-2D kagome superconductor CsV3 Sb5 exhibits large AHE accompanying with the charge-density-wave (CDW) order which provides us an ideal platform to study the interplay among nontrivial band topology,CDW,and unconventional superconductivity.Here,we systematically investigated the pressure effect of the AHE in CsV3Sb5.Our high-pressure transport measurements confirm the concurrence of AHE and CDW in the compressed CsV3Sb5.Remarkably,distinct from the negative AHE at ambient pressure,a positive anomalous Hall resistivity sets in below 35 K with pressure around 0.75 GPa,which can be attributed to the Fermi surface reconstruction and/or Fermi energy shift in the new CDW phase under pressure.Our work indicates that the anomalous Hall effect in CsV3Sb5 is tunable and highly related to the band structure.
