Abstract

The influence of e_g electrons on resonant x-ray scattering was studied using RE_1-xSr_xMnO₃ (RE: rare earth) thin films having an electron configuration of (t_2g) ³(e_g)^1-x. Based on the rigorous measurements of the Jahn-Teller (JT) distortion incorporating the buckling of the MnO ₆ octahedra, we found that the JT distortion has the dominant effect in accordance with the previous reports. The data regarding the x = 1 sample, in which e_g electrons are absent, scales perfectly well with those regarding x = 0.4 samples, confirming that the role played by e_g electrons is negligible.
