Superconductivity 2015-06-16 v1

Abstract

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-TCT_{\rm C} superconductors. In this paper, we review NMR studies on the structural transition, antiferromagnetic order, spin fluctuations, and superconducting properties of several iron-based high-TCT_{\rm C} superconductors, including LaFeAsO1x_{1-x}Fx_x, LaFeAsO1x_{1-x}, BaFe2_2As2_2, Ba1x_{1-x}Kx_xFe2_2As2_2, Ca0.23_{0.23}Na0.67_{0.67}Fe2_2As2_2, BaFe2_2(As1x_{1-x}Px_x)2_2, Ba(Fe1x_{1-x}Rux_x)2_2As2_2, Ba(Fe1x_{1-x}Cox_x)2_2As2_2, Li1+x_{1+x}FeAs, LiFe1x_{1-x}Cox_xAs, NaFeAs, NaFe1x_{1-x}Cox_xAs, Ky_yFe2x_{2-x}Se2_2, and (Tl,Rb)y_yFe2x_{2-x}Se2_2.
