Abstract
The structural, optical, and magnetic characteristics of the (CoFe2O4) x – (BaTiO3)100-x (x = 10, 20, 30, 40, 50) nanocomposites prepared using the sol-gel technique were examined. X-ray diffraction data confirm formation of the tetragonal phase for BTO and the spinel phase for CFO for all composites. The magnetic hysteresis loop measurements were performed using a vibrating sample magnetometer at room temperature. All of the composites had improved ferromagnetic characteristics, which are highly influenced by the amount of the CFO phase. The bandgap energy values decreased as the CFO concentration increased. The dielectric constant, loss function and conductivity for samples were measured.
