Exchange couplings across interfaces of hybrid magnetic heterostructures are being considered as unique opportunity for functional materials design. In this study, we show that both coercivity and magnetization of V2O3/Co bilayers are affected by the stress associated with structural phase transition across metal-insulator phase transition in V2O3. The change in coercivity is as large as 76% in a very narrow temperature range. The magnetic properties can be controlled by stress, which is significant for future multiferroic and spintronics applications.
