FIELD: electricity.
SUBSTANCE: tape from amorphous alloy according to the invention is made from the alloy with the composition of the following formula FeaSibBcCd, where 80.5≤a≤83 at.%, 0.5≤b≤6 at.%, 12≤c≤16.5 at.%, 0.01≤d≤ 1 at.% with a+b+c+d=100, with the content of unintentional impurities as well. The tape moulded from the said alloy has surface defects formed on the tape surface along its longitudinal direction which are defined by such parameters as defect length, defect depth and frequency of defect occurrence.
EFFECT: reduction of magnetic losses in a core made from the above amorphous tape after annealing of the tape.
