摘要: The newly discovered iron-based superconductors have triggered renewed enormous research interest in the condensed matter physics community. Nuclear magnetic resonance (NMR) is a low-energy local probe for studying strongly correlated electrons, and particularly important for high-TC superconductors. In this paper, we review NMR studies on the structural transition, antiferromagnetic order, spin fluctuations, and superconducting properties of several iron-based high-TC superconductors, including LaFeAsO1-xFx, LaFeAsO1-x, BaFe2As2, Ba1-xKxFe2As2, Ca0.23Na0.67Fe2As2, BaFe2(As1-xPx)2, Ba(Fe1-xRux)2As2, Ba(Fe1-xCox)2As2, Li1+xFeAs, LiFe1-xCoxAs, NaFeAs, NaFe1-xCoxAs, KyFe2-xSe2, and (Tl,Rb)yFe2-xSe2.
