 note = {Improvement of high frequency magnetic properties was tried with success for Co-based amorphous ribbons. Process of the improvement is as follows. First, control of domain structure was examined and it was found that field annealing under magnetic field applied in the transverse direction of ribbon creates a ladder-like domain structure. This domain structure improves permeability and magnetic loss in the frequency range larger than 1 MHz. Insulation between ribbons results in further improvement in permeability and magnetic loss. Although reduction of ribbon thickness does not cause remarkable improvement in high frequency magnetic properties when ribbons are not insulated each other, it increases permeability and decreases magnetic loss remarkably when ribbons are insulated. The maximum permeability of 1000 at 10 MHz was obtained for 6. 8μm thick domaincontrolled ribbons with insulation. This value is about tow times as large as that conventional Mn-Zn ferrites., 長崎大学工学部研究報告, 22(38), pp.25-32; 1992},
