    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.

    摘要： A magnetic recording system for recording signals onto coat-type magnetic tape using magnetic powder by using a magnetic head, and a magnetic recording system for recording signals onto a coat-type magnetic disk using magnetic powder by running magnetic head in contact with the disk, are disclosed. The magnetic tape has a coercive force Hc of 2000 to 3800 Oe in the former system, while the magnetic disk has a coercive force He of 2000 to 3500 Oe in the latter system. In both systems, signals are recorded by using a magnetic head using magnetic core members having a saturation magnetic flux density of 15 kG or greater. The magnetic core member having the saturation magnetic Flux density of 15 kG or greater is exemplified by a material expressed by a composition formula (Fe.sub.95.5 Al.sub.1 V.sub.0.5 Nb.sub.0.5 Cu.sub.0.5 Ru.sub.2).sub.92 N.sub.6 O.sub.2.
