Thermodynamic signatures of a field-induced ordered intermediate phase in Na $_{2}$ Co $_{2}$ TeO $_{6}$

Prashanta K. Mukharjee, Sebastian Erdmann, R. Kalaivanan +4

The honeycomb cobaltate Na $_{2}$ Co $_{2}$ TeO $_{6}$ has recently been proposed as a candidate material for hosting field-induced quantum spin liquid (QSL) behavior. Here, we present a comp…

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 $T_{N} = 26.7 K$ , the honeycomb cobaltate Na $_{2}$ Co $_{2}$ TeO $_{6}$ is predicted to enter a Kitaev spin liquid state w…

Spin waves in Na $_{2}$ Co $_{2}$ TeO $_{6}$ studied by high-frequency/high-field ESR: Successes and failures of the triple- $q$ model

Luca Bischof, Jan Arneth, Raju Kalaivanan +3

The Kitaev candidate material Na $_{2}$ Co $_{2}$ TeO $_{6}$ is proposed to be proximate to a quantum spin liquid state but a suitable spin model and the nature of its ground states are still…
