We studied the influence of the AC current flowing through the magnetically bistable Co-rich microwire on the magnetization dynamics. We used previously developed Sixtus-Tonks modified set-up for evaluation of the domain wall (DW) velocity within the microwire, but instead of the magnetizing solenoid we used the current flowing through the microwire. We observed that the AC current flowing though the sample produces the remagnetization of the sample by fast domain wall propagation along the microwire. Estimated DW velocity is about 4.5 km/s, being similar and even higher to that reported for the magnetic field driven domain wall propagation in Fe and Co-rich microwires. Observed current induced DW propagation through the microwire we explained considering the magnetostatic interaction between the outer circumferentially magnetized shell and the inner axially magnetized core.
