Piezoelectrically enhanced exchange bias in multiferroic heterostructures

Abstract

We propose a multiferroic tri-layer structure in which two magnetic layers are epitaxially constrained on a bottom piezoelectric substrate. In this structure, the exchange bias is observed due to interface spin coupling between the two magnetic layers. We also show that the exchange bias is significantly modulated by the application of an external electric field at room temperature, and the modulation in exchange bias is reproducible and reversible.
