Multiferroic nanocomposite fabrication via liquid phase using anodic alumina template

We report a novel and inexpensive fabrication process of multiferroic nanocomposite via liquid phase using an anodic alumina template. The sol-gel spin-coating technique was used to coat the template with ferrimagnetic CoFe(2)O(4). By dissolving the template with NaOH aqueous solution, a unique nano...

Descripción
Sumario:We report a novel and inexpensive fabrication process of multiferroic nanocomposite via liquid phase using an anodic alumina template. The sol-gel spin-coating technique was used to coat the template with ferrimagnetic CoFe(2)O(4). By dissolving the template with NaOH aqueous solution, a unique nanotube array structure of CoFe(2)O(4) was obtained. The CoFe(2)O(4) nanotube arrays were filled with, and sandwiched in, ferroelectric BaTiO(3) layers by a sol-gel spin-coating method to obtain the composite. Its multiferroicity was confirmed by measuring the magnetic and dielectric hysteresis loops.
