Pulsed laser deposition and characterization of multilayer metal-carbon thin films

► Co-DLC multilayer thin films have been deposited by PLD. ► Co-particles of different sizes are embedded in DLC matrix. ► Raman spectra contain characteristics D- and G-bands of DLC films. ► VSM analysis reveals Co-C multilayer films show ferromagnetic behaviour. ► Optical band gaps of DLC films can be tuned by varying Co-content.
