## Description

- description: "Transition-metal ions with 5d2 electronic configuration in a cubic
    crystal field are prone to have a vanishing dipolar magnetic moment but finite
    higher-order multipolar moments, and they are expected to exhibit exotic physical
    properties. Through an investigation using resonant inelastic X-ray scattering
    (RIXS), Raman spectroscopy, and theoretical ligand-field (LF) multiplet and ab
    initio calculations, we fully characterized the local electronic structure of
    Ba2CaOsO6, particularly, the crystal-field symmetry of the 5d2 electrons in this
    anomalous material. The low energy multiplet excitations from RIXS at the oxygen
    K edge and Raman-active phonons both show no splitting. These findings are consistent
    with the ground state of Os ions dominated by magnetic octupoles. Obtained parameters
    pave the way for further realistic microscopic studies of this highly unusual
    class of materials, advancing our understanding of spin-orbit physics in systems
    with higher-order multipoles.\r\n"
