|Title:||Local structure in LaMnO3 across the Jahn-Teller transition|
|Abstract:||We report on an EXAFS study of the local environment of manganese atoms in LaMnO3 across the cell ordering transition temperature. During the EXAFS analysis the phase derivative method was used prior to conventional fits in order to prevent possible mistakes arising from the correlation between parameters in the fitting method. The combination of the two procedures assert the result that the local splitting in the Mn-O distance is maintained above the Jahn-Teller transition and support the order-disorder character predicted for this transition in LaMnO3.|
