Interplay between multipolar spin interactions, Jahn-Teller effect and electronic correlation in a $J_{eff}=\frac{3}{2}$ insulator

Dario Fiore Mosca, Leonid V. Pourovskii, Beom Hyun Kim +5

In this work we study the complex entanglement between spin interactions, electron correlation and Janh-Teller structural instabilities in the 5d${}^1$ $J_{eff}=\frac{3}{2}$ spin-orb…
