Abstract
A soft magnetic film and a soft magnetic multilayer film of high saturation magnetization having an excellent soft magnetic property and a magnetic device use the same by providing an Fe—N thin film formed on a substrate with a configuration such that the main phases are &agr;-Fe and &ggr;′-Fe N, the crystal grain sizes of the &agr;-Fe phase and the &ggr;′-Fe N phase are reduced to as fine as not more than 10 nm, the spacings of the lattice plane (110) of &agr;-Fe parallel to the film surface and the lattice plane (200) of &ggr;′-Fe N are expanded compared to those in the condition where there is no lattice strain, and the spacing of the lattice plane (111) of &ggr;′-Fe N is contracted compared to that in the condition where there is no lattice strain.
