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…
