Polaron-driven switching of octupolar order in doped 5d${}^2$ double perovskite

Dario Fiore Mosca, Lorenzo Celiberti, Leonid V. Pourovskii +1

We investigate how doping-induced small polarons impact the low-temperature multipolar orders of the $5d^2$ double perovskite Ba${}_2$CaOsO${}_6$. By computing intersite exchange inter…
