Study of the Fermi surface in Kagome Superconductor AV$_3$Sb$_5$(A = K,Rb,Cs) by de Haas-van Alphen and Shubnikov-de Haas effect
ORAL
Abstract
The recent discovery of novel charge density wave (CDW) Kagome superconductor AV$_3$Sb$_5$(A = K,Rb,Cs) have attracted great interest. We measured the de Haas-van Alphen effect of AV$_3$Sb$_5$ by using torque magnetometry and Shubnikov-de Haas (SdH) effect by using proximity detector oscillator (PDO) circuits under intense magnetic fields. Combining both dHvA and SdH effect, we provide a comprehensive study of the Fermi surface with the CDW gap considered.
