Thin film

Patent Granted PROBLEM TO BE SOLVED: To provide a high-frequency magnetic thin-film and a high-frequency magnetic device using the magnetic thin-film, wherein its good high-frequency characteristic is obtained, while suppressing its film thickness and reducing its eddy-current loss. ; SOLUTION: With respect to the high-frequency magnetic thin-film, even in a region WA wherein a film-thickness tAF of its antiferromagnetic layer 16 is small, the value of an intensity Jc of its switched connection which is obtained from its magnetic resonance is increased (cf. black circular points).
