Description |
We have thoroughly investigated the oxygen loss in PrMnO3 and BaMnO3 , the end members of the AMnO3 system, on in situ heating in a reducing atmosphere. This
was done to drive some oxygen out from them and thus possibly alter the valence of the Mn cation. Sample characterization was done through X-ray diffraction and SEM
measurements. The core-level photoemission point to oxygen loss from only BaMnO3 changing some of Mn4+ to Mn3+ in it, transfer of some spectral weight to the highly
localized Fehrenbacher–Rice states and an increased Mn 3d–O 2p hybridization. Magnetization measurements show that at low temperatures, the samples depict a canted antiferromagnetic ordering.
