RT Journal Article T1 Spin–Orbit Coupling Controlled Ground State in the Ir(V) Perovskites A2ScIrO6 (A = Ba or Sr) A1 Kayser González, Paula A1 Kennedy, Brendan A1 Ranjbar, Ben A1 Kimpton, Justin A1 Avdeev, Maxim AB The structural and magnetic properties of the two Ir(V) perovskites Ba2ScIrO6 and Sr2ScIrO6 were established. The structures were refined using a combined neutron and synchrotron data set. At room temperature the former has a cubic structure in space group Fm3̅ m with a = 8.1450(3) Å, and the latter is monoclinic in P21/n with a = 5.6606(3) Å, b = 5.6366(3) Å, c = 7.9720(4) Å, and β = 89.977(5)°. Magnetization measurements show both oxides have magnetic moments close to zero as a consequence of strong spin−orbit coupling that results in a Jeff ≈ 0 ground state. The distortion of the IrO6 octahedra in Sr2ScIrO6 is insufficient to generate crystal field splitting strong enough to quench the spin−orbit coupling PB Royal Society of Chemistry SN 0020-1669 YR 2017 FD 2017 LK https://hdl.handle.net/20.500.14352/93611 UL https://hdl.handle.net/20.500.14352/93611 LA eng NO Paula Kayser, Brendan J.
