Abstract :
When a Vicalloy wire (40wt%Fe-50Co-10V) is twisted, the coercivity reduces due to large stress. The pulse-inducing characteristics and domain wall propagation are investigated utilizing this effect on such compound magnetic wire. We find that the generating point of inverse nucleation varies according to the strength of set field Hs and the demagnetizing field near the end of the wire, when the entire compound magnetic wire is excited by an asymmetrical field. Moreover, we find that the velocity of domain wall propagation in the smaller coercivity layer to be 400-500 (m/s) at Hs=16-25 Oe
