抄録

Graded nitrogen concentration is suitable to obtain iron nitride with giant magnetization. Rf sputter deposition was applied to prepare both multilayered and granular thin films in the Fe-Al-N ternary system. A giant magnetization component was observed at the multilayered interface because of the iron nitride formed in a solid state reaction between Fe and AlN layeres. A small amount of nitrogen in AlN was supplied to the α-Fe forming iron nitride reaction layer with a nitrogen concentration gradient through the interface. A granular film with α-Fe dispersed in the amorphous matrix was also obtained by annealing the reactive sputter codeposited Fe-Al-N ternary thin film in a H₂ flow at 500°C. They showed a soft ferromagnetic behavior of α-Fe.
