Abstract: Magnetoelectric CoFe2O4/BaTiO3 composite nanotubes with lengths of about 100 μm and diameters of about 100, 200, and 300 nmwere prepared by a sol-gel template method. The coexistence of spinel CoFe2O4 (CFO) and perovskite BaTiO3 (BTO) phases in the composite (CFO/BTO) nanotubes was revealed by X-ray diffraction (XRD) and selected area electron diffraction (SAED) patterns. Transmission electron microscopy (TEM) confirmed that the nanocomposite had a tubular microstructure. Magnetic properties of the CFO/BTO composite nanotubes were similar to the properties of pure CFO nanotubes. The ferroelectric properties of the composite nanotubes were equivalent to the ferroelectric properties of pure BTO nanotubes.
