Magnetic properties of FeMoN, FeMoTaN, FeTaN and FeTaC films deposited by DC magnetron reactive sputter were investigated, and correlated with their microstructure. FeMoN films were not showen the soft magnetic properties, because of generated Fe₂Mo, Fe_(3-2)N and Fe₄N phases. Ta added films, however, effectivly retarded the α-Fe grain growth and suppressed the generation of Fe nitrides or carbides during heat treatement. The soft magnetic properties of Bs: 15 kG, Hc: 0.25 Oe, μ' 4000(at 5 ㎒), and Bs: 14.5 kG, Hc: 0.25 Oe, μ': 2700 (5㎒) were observed in Fe_(78.8)Ta_(8.5)N_(12.7) and Fe_(75.6)Ta_(8.l)C_(16.3) films, respectively.
