On investigating the longitudinally driven GMI effect of the DC annealed Fe36Co36Nb4Si4.8B19.2 alloy ribbon, the current density was 3.2x10(7) A/m(2), the GMI effect responds sensitively (the sensitivity is as high as 2440.2%/(A center dot m(-1))) to weak magnetic field after a 600-second annealing. The experimental result shows that the sensitivity is closely related to annealing current density, driven current frequency and eroded thickness.
