Abstract
Nowadays the novel ambitious studies dedicated to magnetic materials for sensing technologies highlights the importance of understanding the ways of control the magnetization process. Among variety of soft magnetic materials with fast magnetization process the cheap in production and ultra magnetically soft Fe-based ferromagnetic glass-coated microwires stands out.
In this paper, we experimentally studied the domain wall (DW) motion in amorphous Fe77.5Si7.5B15 and Fe77Si10B10C3 ferromagnetic glass-coated microwires. Using the modified Sixtus-Tonks method the influence of the inhomogeneities distribution and the effect of stray fields on the parameters of DW motion (velocity, local nucleation fields) have been evaluated. Three types of DW motion mechanism were firstly identified. And the model of DW velocity tuning with the mechanical defects influence is presented. This study could lead to decrease the response time of sensitive devices which are based on magnetic domain wall motion mechanism.
