Doping and bond length contributions to Mn K-edge shift in La_(1-x)Sr_xMnO_3 (x = 0-0.7) and their correlation with electrical transport properties

摘要

The room temperature experimental Mn K-edge X-ray absorption spectra of La_(1-x)Sr_xMnO_3 (x = 0-0.7) are compared with the band structure calculations using spin polarized density functional theory. It is explicitly shown that the observed shift in the e
