High spin polarization induced by the interface hybridization in Co/C composite films

Co/C composite films with 10at.% Co were fabricated by facing-target sputtering and postannealed in vacuum at 300–650°C for 1.5h. Co nanoparticles are dispersed in amorphous carbon matrix and Co–C compounds exist at the interface between Co nanoparticles and carbon matrix. Negative magnetoresistance...
