Structural, electrical and magnetic studies of Co:SnO2 and (Co,Mo):SnO2 films prepared by pulsed laser deposition

► Codoping of SnO2 films with Co and Mo. ► Reversion of the blue shift trend of Co-doped SnO2 films by Mo codoping. ► Assessment of codoping of SnO2 with Co and Mo for RT ferromagnetism.
