The microstructure and magnetic properties of FePt and Fe/FePt polycrystalline thin films with high coercivity were investigated. The L1 ₀ FePt particulate film deposited on a heated amorphous SiO ₂ substrate was found to show a large coercivity (H_c) of 23 kOe. The morphological change from particulate to continuous showed a minute decrease in the H_c. The result of the exchange coupling of the Fe and FePt layers show an increase of remanence and energy product.
