Abstract  (Fe,Ti)-N films with high content of Fe16N2 phase are prepared by facing target sputtering. Influences of doped titanium content on the structure and magnetic properties of Fe-N films are investigated. According to XRD and TEM results, optimum Ti additions enhance the formation of the 16:2 nitride, the values of saturation magnetization Bs for (Fe,Ti)-N films with Ti atomic fraction of 0—25% are larger than that for pure bcc iron, the maximum value for Bs is 2.68 T for the sample with 10% Ti, this value is 20% larger than that for pure bcc iron.

Key words:  facing target sputtering      Fe16N2 thin film      Ti doping      magnetic property      structure
