Modeling, simulation and synthesis of multiferroic magnetoelectric CoFe2O4/BaTiO3 composite nanoparticles

Optical properties of cobalt ferrite (CoFe2O4)/barium titanate (BaTiO3) nanoparticles are modeled and simulated utilizing density functional theory (DFT) finite element analysis (FEA) intended for various particle sizes. The absorption maxima electronic excitations is red-shifted from 259.51 nm to 315.27 employing quantum mechanical approach 260 280 using analysis, corresponding enlarging sizes 8 50 nm. measured corresponded well the results longer wavelengths 302.02 321.28 accompanied by an increment in 30 FEA simulated, DFT experimentally extracted optical band gap energies were as obtained compared. Additionally, ferromagnetic behavior CoFe2O4/BaTiO3 was investigated.
