The swift heavy ion irradiated La0.9Mn0.8Fe0.2O3 (La-deficient) system with 200 Mev Ag16 + ion beam at fluence 5 × 1012 ions/cm2 was studied with X-ray diffraction (XRD) and Mössbauer spectroscopic measurements. Comparison of Mössbauer parameters with those of unirradiated sample showed an increase in line width on irradiation which may be due to reduction in particle size as well as due to creation...
We investigate the electronic structures of hole-doped, La0.7Ca0.3MnO3, and electron-doped, La0.7Ce0.3MnO3, manganites by x-ray absorption near edge structure (XANES) spectroscopy at the O and Mn K-edges. While, the O K-edge XANES results indicate that Ca and Ce doping induce holes in O 2p derived states, the Mn K-edge XANES do not give any evidence for creation of the Mn4+ (or Mn2+) ions by Ca (or...
