A heat treatment was carried out in a pressurized condition on an amorphous metal ribbon containing Fe and Co as main components and being represented by the general formula : (Co (1-c) Fe c ) 100-a-b X a Y b . (In the formula, X represents at least one species of element selected from Si, B, C and Ge, Y represents at least one species of element selected from Zr, Nb, Ti, Hf, Ta, W, Cr, Mo, V, Ni, P, Al, Pt, Rh, Ru, Sn, Sb, Cu, Mn and rare earth elements, c, a and b satisfy 0 ‰ c ‰ 0.2, 10 < a ‰ 35 and 0 ‰ b ‰ 30, respectively, and a and b are represented in terms of atomic %.) By carrying out a heat treatment in a pressurized condition in the same manner on a magnetic substrate comprising an amorphous metal ribbon and a heat resistant resin or a laminate of the substrates, not only the magnetic properties but also the mechanical properties and the processability are improved. They are applied in antennas, which are devices that convert an electric wave to an electric signal, rotors and stators of motors and so on.
