Abstract

We have found that a significant change in the local structure of (Formula presented) occurs between 80 K and temperatures above the Curie temperature, (Formula presented) K. Near-edge x-ray-absorption spectra exhibits changes between 80 K and above (Formula presented). X-ray-absorption fine structure reveals differences between the nearest-neighbor Mn-O bond distributions at 80 K and above (Formula presented). The single-site distribution at low temperature becomes a complex, multi-site distribution above (Formula presented). The observed change is consistent with proposed small polaron related local Jahn-Teller distortions for (Formula presented).
