Neutron diffraction and inelastic neutron scattering investigations of the ordered double perovskite Ba2PrIrO6
Neutron diffraction and inelastic neutron scattering investigations of the ordered double perovskite Ba2PrIrO6
High-resolution neutron-powder diffraction data show that the double perovskite Ba2PrIrO6 is cubic at ambient temperatures in space group Fm m. Below TN=71 K the compound orders antiferromagnetically with magnetic moments of 0.43(2) ?B at 6 K, on both the Pr4+ and the Ir4+ sites, oriented along the cubic a-axis. Inelastic neutron scattering at 105 K reveals a strong peak at 276 meV and a weak transition at 366 meV. The former is consistent with the crystal field splitting of the Pr4+ ground state under the cubic point symmetry, while the latter peak is due to the intermultiplet transition between the ground state and excited state.

Abstract
High-resolution neutron-powder diffraction data show that the double perovskite Ba2PrIrO6 is cubic at ambient temperatures in space group Fm m. Below TN=71 K the compound orders antiferromagnetically with magnetic moments of 0.43(2) ?B at 6 K, on both the Pr4+ and the Ir4+ sites, oriented along the cubic a-axis. Inelastic neutron scattering at 105 K reveals a strong peak at 276 meV and a weak transition at 366 meV. The former is consistent with the crystal field splitting of the Pr4+ ground state under the cubic point symmetry, while the latter peak is due to the intermultiplet transition between the ground state and excited state.
