Eclipsing Kitaev: off-diagonal exchange governs the correlated high-field phases of ${\hat{I}}^2$-Li${}_2$IrO${}_3$

Vikram Nagarajan, Ioannis Rousochatzakis, Yuanqi Lyu +9

We report a high-field thermodynamic study of the hyperhoneycomb Kitaev material ${\hat{I}}^2$-Li${}_2$IrO${}_3$, using magnetotropic susceptibility to resolve its low-temperature field-angle p…
