Abstract

Multiferroic NiFe (∼30 nm)/Pb(Mg_1/3Nb_2/3)O ₃-PbTiO₃(PMN-PT, ∼220 nm) bilayered thin films were grown on common Pt/Ti/SiO₂/Si substrates by a combination of off-axis magnetron sputtering and sol-gel spin-coating technique. By using AC-mode magneto-optical Kerr effect technique, the change in the Kerr signal (magnetization) of the NiFe upon applying a low-frequency AC voltage to the PMN-PT film was in situ acquired at zero magnetic field. The obtained Kerr signal versus voltage loop essentially tracks the electromechanical strain curve of the PMN-PT thin film, clearly demonstrating a strain-mediated converse magnetoelectric coupling, i.e., voltage-modulated magnetization, in the NiFe/PMN-PT nanocomposite thin films.
