Abstract
The effect of vanadium (V) doping with various concentrations (x= 12.50%, 25%, 50%, 75%) on the physical properties ofBaTiO3perovskite is examined using the spin polarized theory.The electronic band structure (BS) for both states reveal that all Ba0.875V0.125TiO3, Ba0.75V0.25TiO3,Ba0.5V0.5TiO3 and Ba0.25V0.75TiO3 compounds are half-metallic ferromagnetic (HMF) materials. The results showed that V play a significant role in the HMF behavior ofBa1-xVxTiO3compound. In addition, the magnetic characteristics confirm the integer values of magnetic moment of all mentioned compounds. In optical properties, reflectivity R (ω), optical absorption α (ω), dielectric function ɛ (ω), extinction coefficient k (ω), and refractive index n (ω) are also calculated. The complete set of optical parameters suggests the use of mentioned material in the visible-ultra violet optoelectronics devices. Based on the half metallic (HM) results of V doped BaTiO3 is capable for spintronics applications.
