On the Structure of Vacancy Ordered Superconducting Alkali Metal Iron Selenide

P. Zavalij, Wei Bao, X. F. Wang +9

With single crystal X-ray diffraction studies, we compare the structures of three sample showing optimal superconductivity, K0.774(4)Fe1.613(2)Se2, K0.738(6)Fe1.631(3)Se2 and Cs0.7…

A Novel Large Moment Antiferromagnetic Order in K0.8Fe1.6Se2 Superconductor

Wei Bao, Q. Huang, G. F. Chen +5

The discovery of cuprate high Tc superconductors has inspired searching for unconventional su- perconductors in magnetic materials. A successful recipe has been to suppress long-ra…

Superconductivity and normal state properties of single-crystalline Tl0.47Rb0.34Fe1.63Se2 as seen via 77Se and 87Rb NMR

L. Ma, G. F. Ji, J. Zhang +5

We report both 77Se and 87Rb NMR studies on Tl0.47Rb0.34Fe1.63Se2 single-crystalline superconductors (T_c about 32 K). Singlet superconductivity is decisively determined by a sharp…

77Se NMR study of pairing symmetry and spin dynamics in KyFe2-xSe2

Weiqiang Yu, L. Ma, J. B. He +4

We present a 77Se NMR study of the newly discovered iron selenide superconductor KyFe2-xSe2, in which Tc = 32 K. Below Tc, the Knight shift 77K drops sharply with temperature, prov…
