Structural, magnetic and optical properties of Ni-doped TiO2 thin films deposited on silicon(100) substrates by sol–gel process

•Ni doping decreases the activation energy for the anatase-to-rutile transformation.•With increasing Ni content, the reversible ferromagnetism is found.•Sharp decrease of the EOBG at low Ni content is mainly related to phase composition. Ni-doped TiO2 films were deposited on Si(100) substrates by so...
