Magnetic and electric properties of C-Co thin films prepared by vaccum arc technique

► Cobalt doped carbon thin films have been deposited by pulsed anodic electric arc technique. ► The films are composed of well-crystallized cobalt layers and complex graphitic microstructure. ► An insulating to a metallic state transition at 60 K is observed. ► The magnetic susceptibility measurements show anomalous behaviour around 60 K.
