Figure 4: Temperature dependence of the local Fe-Se and Fe-Fe distances obtained from the least-squares fitting of the in-plane polarized Fe K-edge EXAFS oscillations.

From: Temperature dependent local atomic displacements in ammonia intercalated iron selenide superconductor

Figure 4

Inset shows a sketch of the local coordination environment around Fe atom. The dashed line is a guide to the eyes. The error bars represent uncertainties estimated by analyzing different EXAFS scans and considering correlations between different fit parameters.
