Abstract

Exchange bias (EB) effect has been widely applied in magnetoelectronic devices such as magnetic tunneling junctions and spin valve sensors. Nowadays, the EB related flexible magnetic multilayers have found their application in wearable electronics, which are stretchable and bendable, and hence are closely strain related [1, 2]. Therefore, the investigation on the strain-mediated multi-field control of magnetism in the EB bilayers is of great significance for the development of flexible mag-netoelectronic devices [3]. In this study, we utilized flexible ferroelectric polyvinylidene fluoride (PVDF) membranes to improve the efficiency of strain transfer from substrate to EB heterostructure, and studied the thermal deformation and electric field control of the magnetic behaviors of FeGa/IrMn heterostructures.
