Description
The advancement of spintronics, a technology that leverages the electron’s spin in addition to its charge, demands materials with unique combinations of magnetic and electronic properties. Cobalt (Co)-doped titanium dioxide (TiO₂) has emerged as a promising candidate for such applications due to its potential to exhibit room-temperature ferromagnetism alongside semiconducting behaviour. This study explores the synthesis of Co-doped TiO₂ using the solid-state reaction method, aiming to optimize its structural, optical, and magnetic properties for spintronic functionality. Characterization techniques such as XRD, FTIR, SEM, TEM, UV-Vis spectroscopy, and SQUID magnetometry were employed to analyse the effects of cobalt doping on TiO₂. The results reveal successful Co incorporation into the TiO₂ lattice, leading to lattice distortions, bandgap narrowing, and enhanced magnetic behaviour. These findings highlight the critical interplay between doping concentration, structural integrity, and functional properties. The study concludes that Co-doped TiO₂ exhibits the necessary attributes for next-generation spintronic devices, offering a promising platform for integrating magnetic and electronic components.
