    Abstract

    We measured the electric resistance of KxFe2-ySe2 which is said to have two SC dome. The measurement was performed at 1-14 GPa and at low temperature down to 1 K and the samples have different states of Fe-vacancy by annealing. From results of the measurements, we observed SC-like behaviour at over 11 GPa. The behaviour at higher temperature than Tc indicates that there are two SC phases.
