Structural characterization of Fe-N films prepared by laser ablation

Fe-N films were deposited on glass substrates at temperatures between 20 and 250/spl deg/C in a wide range of nitrogen pressure by KrF excimer laser ablation. Magnetic properties of the Fe-N films are discussed associated with the film structure. Saturation magnetization over 2000 emu/cm/sup 3/ with a decreased coercivity is observed in bct Fe-N films with high crystal orientation prepared at a substrate temperature of 250/spl deg/C.
