Anisotropy Magnetoelectric Coupling in NiFe₂O₄/Bi₅Ti₃FeO₁₅ 0‐3 Type Nanocomposite Films

Multiferroic NiFe₂O₄/Bi₅Ti₃FeO₁₅ (NFO/BTFO) 0‐3 type nanocomposit films are synthesized by combining hydro‐thermal and sol‐gel methods. Structure, ferroelectric, magnetic, and magnetoelectric properties for the nanocomposite films are investigated. High magnetoelectric coupling effect has been obtained at room temperature, which is originated from the stress transfer between two different components. Such 0‐3 type structure can effectively depress the clamp effect from the substrate. Moreover, the nanocomposite films obtain anisotropy magnetic and magnetoelectric properties. The nanocomposite films can be potentially applied in sensitive magnetoelectric sensors.
