Abstract

High resolution Mn K-beta emission spectra provide a direct method to probe the effective spin state and charge density on Mn sites. Direct
comparison of MnF2 and MnO reveals significant changes due to the degree of covalency. The detailed shape and energy shi of thr spectra for the
perovskite LaMnO3 and CaMnO3 compounds are found to be very similar to Mn2O3 and MnO2, respectively. Detailed Mn K-beta X-ray emission results on
La1-xCaxMnO3 can be well fit by linear superpositions of the end member spectra. However, for x < 0.3, a retarded response is found. No evidence for Mn2+ is
found
