Hidden spin-orbital order in the Kitaev hyperhoneycomb $\beta$-Li${}_2$IrO${}_3$

Alejandro Ruiz, Vikram Nagarajan, Mayia Vranas +8

We report the existence of a phase transition at high temperature in the 3D Kitaev candidate material, $\beta$-Li${}_2$IrO${}_3$. We show that the transition is bulk, intrinsic and orders…
