Abstract
The charge density distribution of Nd0.35Sr0.65MnO3 has been investigated by means of the maximum entropy method (MEM) using the synchrotron radiation (SR) X-ray powder diffraction data. In this compound, the anisotropic optical spectra reported by Tobe et al. [Phys. Rev. B 67 (2003) 140402(R)] suggest that the d3z2−r2 orbital-ordering survives even at 600 K (>>TN=260 K). Consistently, we observed an anisotropic charge density distribution around the Mn ion at 30 K (<<TN), indicating the long-range ordering of the d3z2−r2 orbital. At 300 K (≥TN), however, the charge density distribution becomes isotropic, suggesting the disappearance of the long-range orbital ordering.
