Abstract
We studied the magnetization switching in magnetically bistable amorphous ferromagnetic microwires. We observed quite fast domain wall propagation along the microwires and a correlation between the magnetoelastic anisotropy, distribution of the local nucleation eld along the length of microwire and the domain wall dynamics. We observed that both DW velocity and the range of elds, limiting single DW dynamics, can be manipulated by internal or applied stresses and by annealing. We also observed that under certain conditions a controllable domain wall (DW) collision can be realized in di erent parts of the wire, and that it is possible to manipulate the DW dynamics in a eld-driven regime.
