Abstract
The ability to control magnetism of materials via electric field enables a myriad of technological innovations in information storage, sensing, and computing. We use ionic-liquid-assisted ferroelectric switching to demonstrate reversible modulation of interfacial magnetism in a multiferroic heterostructure composed of ferromagnetic (FM) La<sub>0.8</sub>Sr<sub>0.2</sub>MnO<sub>3</sub> and ferroelectric (FE) PbZr<sub>0.2</sub>Ti<sub>0.8</sub>O<sub>3</sub>. It is shown that ionic liquids can be used to persistently and reversibly switch a large area of a FE film. This is a prerequisite for polarized neutron reflectometry (PNR) studies that are conducted to directly probe magnetoelectric coupling of the FE polarization to the interfacial magnetization.
