Abstract (en)

[origin: EP1615240A2] 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: Fe a Si b B c M x or Fe a Si b B c C d M x 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.
