Amorphous Fe 73.5Cu 1Nb 3Si 13.5B 9 alloy was annealed under stress by DC Joule-heating to induce magnetic anisotropy. The magnetic properties of the treated samples were examined by dynamic hystersis loops
longitudinally driven giant magneto-impedance effect and Mssbauer spectra. The experimental results show that nanocrystallization occurs in the amorphous alloys when the current density is above 4.11×10 7A/m 2
and the annealed samples will be induced transverse magnetic anisotropy under suitable current and stress. The magnetic anisotropy increases with the increasing of annealing current density
which is closely related to the amount of α-FeSi nanocrstalline in the alloy.
