Author(s): Weiqiang Yu, L. Ma, J. B. He, D. M. Wang, T.-L. Xia, G. F. Chen, and Wei Bao We present a ^{77} Se NMR study of the newly discovered iron selenide superconductor K_{y} Fe_{2-x} Se_{2} , in which T_{c} =32 K. Below T_{c} , the Knight shift ^{77} K drops sharply with temperature, providing strong evidence for singlet pairing. Above T_{c} , Korringa-type relaxation indicat... [Phys. Rev.
