We study composites of monodisperse ferrimagnetic nanoparticles (NPs) embedded into ferroelectric barium titanate (BTO) films. The BTO films were prepared by pulsed laser deposition. The composite consists of a stack of two BTO films sandwiching one monolayer of iron oxide NPs. We observe a magnetoelectric coupling due to strain and interface charge co-mediation between the BTO and the NPs. This is demonstrated by measurements of the magnetization as function of DC and AC electric fields.
