| Abstract(in English) | To develop nanocrystalline soft magnetic underlayer (SUL) material with high saturation magnetization and low SUL noise, we studied the properties of an Fe-Si-Al-N film. To obtain SUL with high stray-field stability, the Fe-Si-Al-N film is applied to antiferro/ferromagnetic (AFM/FM) multilayer films. As the results, the following points are clarified: 1) As the composition of FeSiAlN film, with increasing nitrogen flow ratio, Fe is replace with N on constant Al + Si concentration line. 2) With increasing nitrogen content, soft magnetic properties of FeSiAlN film are increased due to nanocrystalline effect. 3) As the grain size of FeSiAlN film is decreased, the SUL noise of FeSiAlN film is reduced. Since subsequent high temperature annealing process is not necessary, this process is promising to be applied for moderate temperature process. 4) In the AFM/FM stacked SUL film, the unidirectionOal exchange energy J_k is decreased with the total magnetization of the film. |
