In this work we study the effect of applied stresses on magnetic‐domain propagation in magnetic amorphous Fe‐Co based microwires using Sixtus–Tonks‐like experiments. The dependence of domain‐wall (DW) velocity, v , measured by the above‐mentioned method shows a roughly linear dependence on applied magnetic field, H . We experimentally studied the effect of applied stresses on single DW dynamics in a number of Fe‐Co rich microwires. Quite fast DW propagation ( v up to 2500 m/s at H about 30 A/m) has been observed in low magnetostrictive Co 56 Fe 8 Ni 10 Si 10 B 16 microwires. Applied and internal stresses result in decreasing of DW velocity. The observed dependences have been discussed considering the magnetoelastic contribution to the DW mobility.
