Nearest-neighbor Kitaev exchange blocked by charge order in electron doped $\alpha$-RuCl${}_3$

A. Koitzsch, C. Habenicht, E. Mueller +9

A quantum spin-liquid might be realized in $\alpha$-RuCl${}_3$, a honeycomb-lattice magnetic material with substantial spin-orbit coupling. Moreover, $\alpha$-RuCl${}_3$ is a Mott insulator,…
