Local antiferromagnetic correlations in the iron pnictide superconductors LaFeAsO{1-x}F{x} and Ca(Fe,Co)2As2 as seen via normal-state susceptibility

We have studied the interplay of magnetism and superconductivity in LaFeAsO${}_{1-x}$F${}_x$ and Ca(Fe${}_{1-x}$Co${}_x$)${}_2$As${}_2$. While antiferromagnetic spin density wave formation is…
