Abstract

The dynamic properties of the magnetic domain walls in amorphous glass‐covered microwires were studied. The samples was Joule annealed with an alternate current at different frequencies and the dynamic behaviour of the samples were studied at different applied stresses. The Landau–Lifshitz–Gilbert damping parameter and the domain wall mobility have shown that the dynamic response can be improved by increasing the annealing current frequency.

## Abstract The influence of glass covering on domain wall propagation in Fe~65~B~15~Si~15~C~5~ amorphous microwires is studied, before and after glass removal. High values of domain wall velocity and mobility have been obtained. The domain wall velocity depends linearly on the driving magnetic fie

## Abstract In the present work we give an overview on the domain‐wall dynamics in amorphous glass‐coated microwires with positive magnetostriction. They are characterized by a peculiar domain structure that allows us to study the magnetization process of a single domain wall. The domain‐wall dynam

We present a method to study the domain wall potential through the thermal activation of the domain wall across the energy barrier. Two contributions to the domain wall potential in amorphous microwires are recognized: magnetoelastic and relaxation. The role of each contribution is studied by measur

## Abstract In the present contribution, we deal with two anomalous effects that have been found in magnetic microwires during the domain‐wall dynamics study. First, there is a negative critical propagation field __H__~0~. Its frequency and temperature dependence is dealt in terms of two domain‐wal
