Unusual multiferroic phase transitions in intrinsically nonmagnetic ferroelectric PbTiO 3 are demonstrated. Misfit strain activates local (anti)ferromagnetism at oxygen vacancies in PbTiO 3 via the orbital symmetry breaking and splitting of the defect electronic states. A nonlinear magnetoelectric effect is present due to magnetic phase transitions coincident with ferroelectric polarization switching, providing a new route to magnetoelectric and multiferroic oxides.
