  • Charge quadrupole order was predicted in several 5d1 and 5d2 double perovskite systems, but experimental verification has been challenging. Here the authors provide experimental and theoretical evidence of simultaneous charge quadrupole order and local structural distortions in Ba2MgReO6.

  • Frustrated quantum magnets have been studied intensely, owing to their potential of hosting exotic quantum magnetism, however, experimental realisation of model systems, such as the spin-1/2 Heisenberg antiferromagnet on an anisotropic triangular lattice is challenging. Here Gen et al demonstrate that the rhenium oxyhalides, A3ReO5X2, though chemical substitution can span a diverse effective spin Hamiltonians.

  • Dynamic Jahn-Teller effect is rarely realized in condensed matter systems. Here, the authors demonstrate its occurrence in Ba2MgReO6, a 5d1 double perovskite, using resonant inelastic x-ray scattering, thermodynamic measurements and quantum chemistry calculations.
