In the present work, the stress-impedance and the stress-resistance for Co68.5Fe4.5Si12B15 amorphous ribbon are reported. The stress-impedance decreases with increasing tensile stress. In contrast, the large stress-resistance appears at high frequency. The value of with F = 20g can reach 31.4% at 5 MHz. The mechanism of the stress-impedance effect is also discussed.
