Angle-resolved photoemission evidence of s-wave superconducting gap in KxFe2-ySe2 superconductor

M. Xu, Q. Q. Ge, R. Peng +7

Although nodeless superconducting gap has been observed on the large Fermi pockets around the zone corner in KxFe2-ySe2, whether its pairing symmetry is s-wave or nodeless d-wave i…

Macroscopic phase segregation in superconducting K0.73Fe1.67Se2 as seen by muon spin rotation and infrared spectroscopy

C. N. Wang, P. Marsik, R. Schuster +8

Using muon spin rotation (\muSR) and infrared spectroscopy we investigated the recently discovered superconductor K0.73Fe1.67Se2 with Tc = 32 K. We show that the combined data can…
