摘要： Disclosed is a soft magnetic thin film having a basic composition of FecoNi or FeCoDy which is specified for use as a single layer film for increasing the saturation magnetic flux density and the coercive force.The soft magnetic properties are achieved by laminating the above defined soft magnetic thin film as the first soft magnetic thin film layer with a second magnetic thin film layer. In this case, crystal structures of the first and the second soft magnetic thin films should appropriately be selected and combined.

摘要： Additive elements are added to Fe-N soft magnetic thin films along with oxygen, so that the thermal stability is remarkably improved. After annealing treatment at approximately 550.degree. C., it is possible to provide an Fe-N soft magnetic thin film with a low coercive force. Similarly, it is also possible to provide a soft magnetic thin film having a low coercive force by introducing a combination of specific types of additive elements to Fe-N soft magnetic thin films. When oxygen is further added to the film, it is also possible to provide a soft magnetic thin film which has very excellent soft magnetic characteristics and good thermal stability. The soft magnetic thin films of the invention have good soft magnetic characteristics, a high saturation magnetic flux density and good thermal stability. A magnetic head of a metal-in-gap type using the soft magnetic thin film is also described.
