Domain Wall Propagation in Co-Based Glass-Coated Microwires: Effect of Stress Annealing and Tensile Applied Stresses

We report our recent results on studies of the effect of magnetic anisotropy induced by stress annealing on the domain wall (DW) dynamics of Co-rich microwires. We observed that the DW velocity of nearly zero magnetostrictive glass-coated microwires can be enhanced either by stress annealing of Co-rich microwires or even under applied tensile stresses to the annealed samples.
