Abstract :
Magnetoelectric composites containing cobalt ferrite (CoFe2O4) and barium–strontium titanate (Ba0.8Sr0.2TiO3) phases were synthesized by solid-state reaction method. The crystal structure and morphology of the composites were examined with X-ray diffraction (XRD) and field emission scanning electron microscope (FE-SEM). Dielectric constant and dielectric loss were studied as a function of frequency and temperature using broadband dielectric measurement system. SQUID magnetometer was used to characterize the magnetic properties of the composites. Dielectric properties were explained in terms of the presence of composite phases of ferrite and titanate. Magnetoelectric properties showed optimum value for a ferrite content of 15 mol%.
