| 英文摘要 | Fe-Ti-N magnetic films were deposited with high sputtering power of 900 W. When the composition (atomic fraction, %) of the film is in the range between Fe-39Ti-8.8N and Fe-3.3Ti-13.5N, the film is composed of alpha' and Ti2N precipitates, the 4piM(s), is higher than that of pure iron, reaches a maximum of 2.38 T and the H-c is reduced to a minimum of 89 A/m. The film could meet the needs of the recording head in the dual-element GMR/inductive heads for 1.55 Gb/cm(2) high storage density. The incorporation of N in alpha-Fe brings about the high saturation magnetization of the alpha'phase. The Ti addition inhibites the equilibrium decomposition of alpha' --> alpha+gamma' and stabilizes the strong ferromagnetic phase alpha'. Because H-c(D) proportional to D-6, the grain size control is very important. The nitrogen induces severe distortion of the a' lattice, which could break the grain to pieces and reduce the grain size. High sputtering power also leads to the formation of fine grain of about 14 mn. Ti2N preferentially precipitated at the grain boundary could pin the grain boundary and prevent the grain growth. The stable temperature of the structure and coercivity is not less than 520 degreesC. |
