Experimental isolated Cu—O contribution to the Cu K-edge XAFS on La2CuO4.1 at 10 K (solid line), fit based on a RDF of Cu—O bonds derived from a two-site potential, as described in the text (dashed line), and fit based on a Gaussian RDF of Cu—O bonds (dotted line). Note the increased deviation between the Gaussian RDF fit and data at high values of k. Inset: detail of the fits and data in the region 10 < k < 16 Å−1. |
