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 NaFe${}_{0.94}$Co${}_{0.06}$As. The low-energy antiferromagnetic spin fluctuations in the normal stat…
