RIXS, XES and XAS studies for electronic structure of rare earth and alkaline earth modified manganite

This article reports on the RIXS (Resonant inelastic X-ray scattering), XES (X-ray emission spectroscopy), and XAS (X-ray absorption spectroscopy) of the LaSr2Mn2O7, La0.95Ba0.05MnO3, and La-1.2(BaCa)(1.8)Mn2O7 at 40 K, 100 K and 300 K. The RIXS spectra of these samples show the presence of Mn in different valence states (Mn2+, Mn3+, and Mn4+) which is associated with the Jahn-Teller distortion due to overlapping between O-2(-) and the unpaired electrons of transition metal Mn. It has also been noticed that the distortion observed in different valence states of Mn with O(2)(-& nbsp;)is found to be suppressed with dropping and the temperature. So, based on aforementioned studies, the Manganites have been considered as a strongly correlated magnetic system which would be useful in magnetic device applications.
