As one of the most fundamental physical phenomena, anomalous Hall effect (AHE) typically occurs in ferromagnetic materials but is not expected conventional superconductors. Here, we have observed a giant AHE kagome superconductor CsV3Sb5 with transition temperature (Tc) 2.7 K. The conductivity reaches up to 2.1*10^4 {\Omega}-1 cm-1 which larger than those metals. Strikingly, emergence exactly follows higher-temperature charge-density-wave (CDW) TCDW ~ 94 K, indicating strong correlation...
In contrast to bulk FeSe superconductor, heavily electron-doped FeSe-derived superconductors show relatively high Tc without hole Fermi surfaces and nodal superconducting gap structure, which pose great challenges on pairing theories in the iron-based superconductors.
