In this talk, we discuss the magnetoelastic and magnetoelectric properties of the quantum spin liquid candidate Na2Co2TeO6. We study the phase diagram of Na2Co2TeO6 using thermodynamic, magnetic, magnetoelastic, and magnetoelectric measurement techniques. We find strong magnetoelastic responses, particularly for in-plane fields are very sensitive indicators of phase transitions, and moderate magnetoelectric response. We contemplate the possibility of using magnetoelectricity in Heisenberg-Kitaev magnets as a new, unique way to extinguish the unwanted long-range order.
