Between Mott and cluster Mott: spin-orbit entangled dimer singlets in Ba $_{3}$ CeRu $_{2}$ O $_{9}$

L. PÃ¤tzold, A. Sandberg, H. Schilling +8

The hexagonal 4d ruthenates Ba3MRu2O9 host structural dimers and exhibit a delicate balance of competing interactions. Hund's coupling, trigonal crystal-field splitting, and hoppin…

Quasimolecular electronic structure of the trimer iridate Ba $_{4}$ NbIr $_{3}$ O $_{12}$

M. Magnaterra, A. Sandberg, H. Schilling +17

The insulating mixed-valent Ir $^{+ 3.66}$ compound Ba $_{4}$ NbIr $_{3}$ O $_{12}$ hosts two holes per Ir $_{3}$ O $_{12}$ trimer unit. We address the electronic structure via resonant inelastic…

Spin-orbital-lattice entanglement in the ideal j=1/2 compound K $_{2}$ IrCl $_{6}$

P. Warzanowski, M. Magnaterra, Ch. J. Sahle +9

Mott insulators with spin-orbit entangled j=1/2 moments host intriguing magnetic properties. The j=1/2 wave function requires cubic symmetry, while a noncubic crystal field mixes j…
