Abstract :

An affordable fabrication process for nanocomposites with considerable multiferroicity has been widely expected. Here, we report the novel and inexpensive liquid-phase fabrication process for BaTiO₃-CoFe₂O₄ (BTO-CFO) multiferroic nanocomposite. An anodization followed by hydrothermal treatment was used to fabricate BTO nanotube arrays. The nanotube arrays were filled with CFO by sol-gel spin-coating or electric-assisted magnetophoretic deposition of CFO nanoparticles prepared by a copreciptation method to obtain multiferroic nanocomposite. The nanocomposite structure was thoroughly observed with electron microscopes and the ferroic properties of the sample were evaluated.
