Competing Interactions and the Effects of Uniaxial Out-of-plane Perturbations in the Honeycomb Antiferromagnet Na${}_2$Co${}_2$TeO${}_6$

J. Arneth, R. Kalaivanan, R. Sankar +2

Despite exhibiting magnetic long-range order below $T_{\mathrm{N}}=26.7\mathrm{K}$, the honeycomb cobaltate Na${}_2$Co${}_2$TeO${}_6$ is predicted to enter a Kitaev spin liquid state w…
