In the presence of strong spin-orbit coupling, honeycomb-layered magnetic materials host a particular type of magnetic interactions known as Kitaev interactions. These are predicted to lead to a topological quantum spin liquid ground state. The material $\ensuremath{\alpha}$-RuCl${}_{3}$ is considered to be close to this Kitaev spin liquid state. Here, the authors discuss the effect of the partial substitution of ruthenium ions in $\ensuremath{\alpha}$-RuCl${}_{3}$ by magnetic chromium ions, which have a much smaller spin-orbit coupling.
