Popis: Electrical field induced electromagnetic properties via strain-mediated magnetoelectric effect were studied in FeCoNi/[Pb(Mg1/3Nb2/3)O3]0.68-[PbTiO3]0.32 (PMN-PT) multiferroic heterostructures. Both the resonance frequency fFMR and the frequency linewidth Δf are electrically tunable with fFMR being varied from 3.8 to 8.1 GHz and Δf from 0.66 to 3.6 GHz. The static magnetic characterization result of the sample before and after poling is also in good agreement with the dynamic magnetic measurement. These results were discussed in details within the framework of the strain-mediated magnetoelectric coupling, which was firmly supported by the electrical field dependence of the in-plane strain measured by a strain gauge.
