Enhanced magnetoelectric coupling in a composite multiferroic system via interposing a thin film polymer

Enhancing the magnetoelectric coupling in a strain-mediated multiferroic composite structure plays a vital role in controlling magnetism by electric fields. An enhancement of magnetoelastic coupling between ferroelectric single crystal (011)cut [Pb(Mg1/3Nb2/3)O-3]((1-x))-[PbTiO3](x) (PMN-PT, x approximate to 0.30) and ferromagnetic poly-crystalline Ni thin film through an interposed benzocyclobutene polymer thin film is reported. A nearly twofold increase in sensitivity of remanent magnetization in the Ni thin film to an applied electric field is observed. This observation suggests a viable method of improving the magnetoelectric response in these composite multiferroic systems. (C) 2017 Author(s).
