Phase Separation, Competition, and Volume Fraction Control in NaFeCoAs
Long Ma, J. Dai, P. S. Wang +9
We report a detailed nuclear magnetic resonance (NMR) study by combined Na and As measurements over a broad range of doping to map the phase diagram of NaFeCo…
Simultaneous optimization of spin fluctuations and superconductivity under pressure in an iron-based superconductor
G. F. Ji, J. S. Zhang, Long Ma +9
We present a high-pressure NMR study of the overdoped iron pnictide superconductor NaFeCoAs. The low-energy antiferromagnetic spin fluctuations in the normal stat…
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…
Local spin fluctuations in iron-based superconductors: 77Se and 87Rb NMR measurements of Tl0.47Rb0.34Fe1.63Se2
Long Ma, G. F. Ji, J. Dai +5
We report nuclear magnetic resonance (NMR) studies of the intercalated iron selenide superconductor (Tl, Rb)FeSe ( K). Single-crystal measurements up to…
