Effect of applied stresses on domain‐wall propagation in glass‐coated amorphous microwires

Abstract

AbstractIn 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 Co56Fe8Ni10Si10B16 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.
