- Abstract
Highly pure butterfly-shaped BiFeO@BaTiO nanotubes have been synthesized through a sol-gel method. An obvious ferromagnetic behavior was obtained at room temperature, with a large coercive field (5,403 Oe) and high Mr/Ms value (0.52). The dielectric permittivity of BiFeO@BaTiO nanotubes was found to be 1919, which is much higher than that of pure BFO nanostructure. The dielectric loss of BiFeO@BaTiO nanotubes is low in the frequency range from 10 Hz to 1 MHz. The maximum magnetoelectric coefficient of BiFeO@BaTiO nanotube is 0.272 μV/cm Oe. Moreover, the BiFeO@BaTiO nanotubes have exhibited a better ferroelectric property with a large band gap of 3.2 eV which demonstrates the core-shell nanostructure.
