ferroelectric oxide shell exhibit a magnetic field-tunable piezoelectric response and ferroelectric coercivity owing to magneto-elastic coupling through the interfacial core-shell boundary. The observed magneto-elastic tuning of the ferroelectric switching is analyzed using a renormalized Landau-Ginzburg stiffness in which a magnetic field-tunable stress concentration is incorporated. These results provide insight into the design of integrated functional devices and magnetoelectric sensors.
