FeCo is a material attracting the interest of many because its very high saturation magnetization (up to 2.45 T). In this study, FeCo nanoparticles assembled films with a matrix (carbon) were prepared by an integrated nanocluster deposition system with a gas aggregation cluster source and dc magnetron co-sputtering guns. The nanoparticles are produced from a Fe{sub 65}Co{sub 35} alloy target. The average particle size is controlled to vary from 5 to 12 nm. The size distribution is less than 10%. Transmission electron microscope images show the change of crystallinity upon online heating. FeCo nanoparticles with cubic shape are formed with online heating. H{sub c} is found to increase with the carbon matrix deposited.
