The microstructures of ion-beam co-sputtered Co-C thin films were studied. As-deposited films whose carbon concentrations were more than 46 at%, consisted of a granular amorphous phase. Successive annealing transformed these films to crystal phase keeping the granular structure. This procedure fabricated fine Co particles 10 nm in diameter surrounded by graphite boundary.
