Large stress-resistance effect at high frequencies in Co68.5Fe4.5Si12B15 amorphous ribbon
Published online by Cambridge University Press: 15 March 2002
Abstract
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 $(R(0)-R(F))/R(0)$ with F = 20g can reach 31.4% at 5 MHz.
The mechanism of the stress-impedance effect is also discussed.
