Abstract

CoPt nanoparticles embedded in nonmagnetic matrices M (M = C, BN) have been obtained by annealing multilayer precursors prepared by sputtering from Co/sub 50/Pt/sub 50/ and M targets in a tandem deposition mode onto Si substrate. The structure and microstructure development of the CoPt/C films has been studied at different annealing stages. Magnetic properties of CoPt with different particle size are investigated with respect to bilayer thickness, annealing conditions, and temperature. The possibility for high density recording media is discussed.
