RIXS interferometry and the role of disorder in the quantum magnet Ba${}_3$Ti${}_{3-x}$Ir${}_x$O${}_9$

M. Magnaterra, M. Moretti Sala, G. Monaco +8

Motivated by several claims of spin-orbit driven spin-liquid physics in hexagonal Ba${}_3$Ti${}_{3-x}$Ir${}_x$O${}_9$ hosting Ir2O9 dimers, we report on resonant inelastic x-ray scattering…
