Development of liquid-phase fabrication of nanotube array-based multiferroic nanocomposite film

摘要

Owing to their unique characteristics, multiferroic materials are expected to be widely used in the next-generation multifunctional devices. In addition to improving their characteristics, developing affordable fabrication processes for multiferroic materials is highly demanded in both industry and academia. In this paper, we show a novel process named electric-assisted magnetophoretic deposition for the fabrication of nanotube array-based multiferroic nanocomposite films. Magnetic nanoparticles were homogeneously deposited on the inner walls of the nanotube array substrate. A BaTiO3-CoFe2O4 nanotube array-based multiferroic nanocomposite film prepared in this work exhibited a magnetoelectric effect originating from the strain transfer between the two components.
