The characteristics of X-ray Diffraction (XRD), Current (I)-Voltage (V), and the Polarization-Electric field (P-E) on the BiFeO₃ (BFO), BaTiO₃ (BTO), and our proposed Multi-Layer (ML) BiFeO₃/BaTiO₃ (BFO/BTO) samples are studied systemically. The influence of these films with and without different external Magnetic (M_ex.) inputs is also investigated. Our proposed multi-ferroic ML BFO/BTO sample has a lower tunneling current (J_g) (~5 × 10³ times) and a stronger magneto-electric effect (an ~25 times higher value of the change of saturated polarization P_s with the M_ex. inputs than the pure multi-ferroic BFO sample. The material properties for ML BFO/BTO samples can be optimized with the combination of the advantages of BFO and BTO thin films. The stronger magneto-electric effect in our proposed ML samples can have many applications such as magnetic sensors, magnetic electric devices, and logic Magneto-Electric Spin–Orbit (MESO) devices.
