Abstract

A magnetic core provided with a shape for a transformer by a cut-lap or step-lap method, which is constituted by an Fe-based amorphous alloy ribbon having excellent magnetic characteristics, which is represented by the general formula: FeaSibBcMx or FeaSibBcCdMx wherein M is Cr and/or Ni, a is 78 to 86 atomic%, b is 0.001 to 5 atomic%, c is 7 to 20 atomic%, x is 0.01 to 5 atomic%, and d is 0.001 to 4 atomic%, (a+b+c+x) or (a+b+c+d+x) being 100.
