Abstract Effects of spin–orbit interactions in condensed matter are an important and rapidly
evolving topic. Strong competition between spin–orbit, on-site Coulomb and crystalline …

We report on our investigation on the magnetism of the iridate double perovskite Sr 2 CoIrO
6, a nominally Ir 5+ Van Vleck J eff= 0 system. Using x-ray absorption (XAS) and x-ray …

Spin–orbit effects in heavy 5d transition metal oxides, in particular, iridates, have received
enormous current interest due to the prediction as well as the realization of a plethora of …

We report resonant inelastic x-ray scattering (RIXS) measurements on ordered double-
perovskite samples containing Re 5+ and Ir 5+ with 5 d 2 and 5 d 4 electronic configurations …

We report an unusual magnetic ground state in single-crystal, double-perovskite B a 2 YIr O
6 and Sr-doped B a 2 YIr O 6 with I r 5+(5 d 4) ions. Long-range magnetic order below 1.7 K …

Recently, the iridate double perovskite Sr 2 YIrO 6 has attracted considerable attention due
to the report of unexpected magnetism in this Ir 5+(5 d 4) material, in which according to the …

Transition metal compounds with the (t 2 g) 4 electronic configuration are expected to be
nonmagnetic atomic singlets both in the weakly interacting regime due to spin-orbit …

We report electron spin resonance (ESR) spectroscopy results on the double perovskite Ba
2 YIrO 6. On general grounds, this material is expected to be nonmagnetic due to the strong …

Vacancy-ordered halide double perovskites hosting 4 d/5 d transition metals have emerged
as a distinct platform for investigating unconventional magnetism arising out of the interplay …

Iridates with the 5 d 4 electronic configuration have attracted recent interest due to reports of
magnetically ordered ground states despite longstanding expectations that their strong spin …
