Anisotropic susceptibilities in the honeycomb Kitaev system $\alpha$-RuCl${}_3$

P. Lampen-Kelley, S. Rachel, J. Reuther +6

The magnetic insulator $\alpha$-RuCl${}_3$ is a promising candidate to realize Kitaev interactions on a quasi-2D honeycomb lattice. We perform extensive susceptibility measurements on s…
