An electric-field modulation of the magnetic properties through converse magnetoelectric effect was reported in Fe films directly grown on BiScO 3 - PbTiO3 (BSPT) ceramics based on the magneto-optical Kerr effect. When an electric field was applied on the piezoelectric BSPT ceramics, the coercive field (Hc) of the ferromagnetic Fe films changed dramatically and an upto 60% change in Hc was observed. The Hc electric field curve essentially tracked the dependence of the piezostrain of the BSPT ceramics on the electric field, which definitely demonstrated the magnetic-mechanical-electric coupling in such film-on-substrate composite structures.
