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…
Microscopic coexistence of superconductivity and antiferromagnetism in underdoped Ba(Fe1-xRux)2As2
Long Ma, G. F. Ji, Jia Dai +5
We use As nuclear magnetic resonance (NMR) to investigate the local electronic properties of Ba(FeRu)As ( 0.23). We find two phase transitions, to…
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…
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…
