Magnetoelastic Contribution in Domain-Wall Dynamics of Magnetically Bistable Microwires

摘要

In this paper, we experimentally studied the effect of applied and residual stresses on the domain-wall (DW) velocity in amorphous Fe–Co-based microwires. We found that application of applied stresses and an increase of internal stresses result in decrease of DW velocity. We assume that in order to achieve higher DW propagation velocity at the same magnetic field and enhanced DW mobility, especial attention should be paid to decrease of magnetoelastic energy.
