Quenched Fe Moment in the Collapsed Tetragonal Phase of CaPrFeAs
Long Ma, G. F. Ji, J. Dai +3
We report As NMR studies on single crystals of rare-earth doped iron pnictides superconductor CaPrFeAs (=0.075 and 0.15). The As spectra…

NMR study of superconductivity and spin fluctuations in hole-doped superconductor Ca1-xNaxFe2As2 (Tc =32 K)
Long Ma, J. S. Zhang, D. M. Wang +4
We report both 23Na and 75As NMR studies on hole-doped Ca1-xNaxFe2As2 superconducting single crystals (x\approx 0.67) with Tc =32 K. Singlet superconductivity is suggested by a sha…

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…
