CoFe2O4–BaTiO3 multiferroic composites: role of ferrite and ferroelectric phases on the structural, magneto dielectric properties
Cobalt ferrite (CoFe 2 O 4 ) and Barium titanate (BaTiO 3 ) nanoparticles have been prepared by the microwave hydrothermal technique at 150 °C/60 min. The synthesized powders have been characterized using transmission electron microscopy, X-ray diffraction (XRD) and fourier transformation infrared s...
