ABSTRACT = {The full potential linearized augmented plane wave (FP-LAPW) approach based 
on the density functional theory (DFT) is employed to know the effect of Co doping on the 
electronic, optical, and magnetic characteristics of BaTi<sub>1-x</sub>Co<sub>x</sub>O<sub>3</sub> at x= 8.33%, 16.66%, 
25%, and 50%. The computed spin-polarized electronic band structure (BS) and the 
density of states (DOS) elucidate that the BaTi<sub>1-x</sub>Co<sub>x</sub>O<sub>3</sub> compound has a ferromagnetic 
semiconductor behavior at all doping concentrations. The results indicate that the magnetic 
moment in BaTi<sub>1-x</sub>Co<sub>x</sub>O<sub>3</sub> is found due to the <i>p-d</i> hybrid orbitals of Co. Moreover, the 
optical features of the Co-doped BTO compound are evaluated by analyzing the refractive 
index, reflectivity, absorption coefficient, optical conductivity, and dielectric constant 
under different concentrations. The outcomes revealed that the BaTi<sub>1-x</sub>Co<sub>x</sub>O<sub>3</sub> compound is 
a good candidate for spintronics and optoelectronic applications.},
