Abstract:
A soft magnetic film containing Fe and N, wherein main phases in the film are &agr;-Fe and &ggr;â€²-Fe4N, mean grain diameters of the &agr;-Fe phase and the &ggr;â€²-Fe4N phase are not more than about 10 nm, spacings of a lattice plane (110) of the &agr;-Fe phase parallel to a film surface and a lattice plane (200) of the &ggr;â€²-Fe4N phase are expanded compared to a respective lattice plane spacing in a condition where there is no lattice strain, and a spacing of a lattice plane (111) of the &ggr;â€²-Fe4N phase is contracted compared to a lattice plane spacing in a condition where there is no lattice strain.
