Coexistence of insulator-like paramagnon and metallic spin-orbit exciton modes in SrIrO${}_3$

Eugenio Paris, Wenliang Zhang, Yi Tseng +13

We probe the spectrum of elementary excitations in SrIrO${}_3$ by using heterostructured [(SrIrO${}_3$)${}_m$/(SrTiO${}_3$)${}_l$] samples to approach the bulk limit. Our resonant inelastic…
