Magnetoelectric Interactions in Composites of Ferrite Films on Lattice-Matched Substrates and Ferroelectrics

This is the authors' abstract. We don't add key points for this paper.

The converse magnetoelectric effect (CME, $i.e.$ the magnetic response to a static electric field) in ferrite-ferroelectric composites is important for an innovative class of voltage-tunable, high-frequency magnetic devices. Technical challenges persist, though, due to weak CME coupling, large ferromagnetic-resonance (FMR) linewidth, and the need for a large bias magnetic field. This study aims to overcome those challenges by using single-crystal-like nickel ferrite films exhibiting high magnetostriction and narrow FMR linewidth. These films present a very high growth-induced magnetic anisotropy field that eliminates the need for a bias field, and facilitates device integration.
