摘要: Abstract The electrical and magnetic properties of rare earth orthoferrites are strongly dependent upon the electronic structure Fe cations. This study investigates as a function composition in LaFe 1− x Ni O 3 using K-edge X-ray absorption spectroscopy at room temperature. Analysis spectra indicates presence 3+ 4+ . concentration increases with increasing content Variations oxidation state have been correlated to those characteristics
