Description

Transition-metal-doped oxides offer a potential route towards magnetic semiconductors which would pave the way for spintronic applications. Although much of the research work has been conducted on Co-doped TiO2, the room temperature magnetic properties of the system are still not well understood [1]. In this study, titanium dioxide (TiO2) thin films were deposited on a silicon substrate and doped with Co ions using ion beam implantation at multiple beam energies to create a uniform dopant layer. Neutron reflectometry and X-ray absorption spectroscopy were conducted at ANSTO to study the magnetic and electronic properties of TiO2 thin films.
