Rønnow, D. F. McMorrow, and F. Mila Sr 3 Ir 2 O 7 is a member of the iridate Ruddlesden-Popper series Sr n + 1 Ir n O 3 n + 1 with electronic properties that interpolate between the insulating single-layer Sr 2 IrO 4 ( n = 1 ) and a metallic compound SrIrO 3 ( n = ∞ ). Using resonant inelastic X-ray scattering (RIXS) experiments, the authors reveal a new magnetic mode and propose a model based on weakly coupled quantum dimers to describe the observed excitation spectrum.
