Short-range order measurements in MgO-FeO and MgO-LiFeO2 solid solutions by DLS simulation-assisted EXAFS analysis

EXAFS analysis is here used to characterize short-range order and local structure in oxide solid solutions by direct measurement of the identity and number of next nearest neighbour cations. Precision is improved through the use of constraints, including simulation-derived interatomic distances.
