Abstract
Disclosed is a FeCoNiN-based soft magnetic thin film composition having the formula Fe Co Ni N , wherein x, y, z and v are expressed in at % and satisfy 41≦x≦55, 18≦y≦27, 19≦z≦32, 0<v≦5, and x+y+z+v=100. The Fe-based ultrafine crystalline soft magnetic thin film composition is prepared by the more simplified method and much more excellent soft magnetic properties in the high-frequency than the conventional soft magnetic thin film compositions.
