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…
Nodeless superconductivity in KFeSe single crystals revealed by low temperature specific heat
Bin Zeng, Bing Shen, Genfu Chen +4
Low temperature specific heat (SH) has been measured in KFeSe single crystals with T = 32 K. The SH anomaly associated with the superconducting transition is mo…
77Se NMR Evidence of Strongly Coupled Superconductivity in K0.8Fe2-xSe2
L. Ma, J. B. He, D. M. Wang +2
We report the 77Se NMR Knight shift and spin-lattice relaxation studies on the superconducting state of the ternary iron selenide K0.8Fe2-xSe2 with Tc~30 K. Just below Tc, the Knig…
23Na and 75As NMR Studies on NaFeAs0.8P0.2 Single Crystals
L. Ma, J. Zhang, D. M. Wang +4
We report our Na and As NMR studies on isovalent phosphorus-doped NaFeAsP ( 33 K) single crystals. Our data suggest a dramatic enhancement of th…
