Do electron distributions with orbital degree of freedom exhibit anisotropy?. Issue 7 (2nd March 2022) - Manjo, Taishun
Abstract : Direct observation of valence electron density reflecting orbital degrees of freedom on partially filled degenerate orbitals. Abstract : Orbital degrees of freedom appear in partially filled degenerate orbitals and are responsible for a variety of physical properties. Although many methods for directly observing orbital states in ordered states have been proposed, it is difficult to determine degenerate orbital states directly. We found that high-precision diffraction data obtained by synchrotron radiation X-rays can be used to observe only the valence electron density distribution with minimal analytical bias. The results obtained using this method clearly showed the anisotropy of the partially filled degenerate 3d orbital states in spinel vanadium oxide FeV2 O4 . The 3d orbital quantum state was successfully determined from this anisotropy.
