摘要：

The nematic susceptibility, chi(phi), of hole-doped Ba1-xKxFe2As2 and electron-doped Ba(Fe1-xCox)(2)As-2 iron-based superconductors is obtained from measurements of the elastic shear modulus using a three-point bending setup in a capacitance dilatometer. Nematic fluctuations, although weakened by doping, extend over the whole superconducting dome in both systems, suggesting their close tie to superconductivity. Evidence for quantum critical behavior of chi(phi) is, surprisingly, only found for Ba(Fe1-xCox)(2)As-2 and not for Ba1-xKxFe2As2-the system with the higher maximal T-c value.
