Here we report on the domain wall dynamics in amorphous glass-coated FeCuNbSiB microwires measured in the temperature range from 77 up to 400 K. At low temperatures below 200 K, the domain wall velocity is proportional to the applied magnetic field.

The domain wall dynamics in the adiabatic regime has been studied. It is shown that the domain wall velocity in the low-field range (when the domain wall interacts with the distributed defects) satisfy the power law: v = S ′( H − H 0 ) β , where

Influence of the directional ordering on magnetization processes in the amorphous Fe44.5Co44.5Zr7B4 alloy was investigated in the temperature region of 27 to 300◦C for stabilization times of up to 1000 min by means of the Perminvar effect. The time

Amorphous magnetic microwires are novel materials, which are characterized by the unique magnetic properties. Their magnetization process runs through the depining and subsequent propagation of the single-domain wall. This allows us to study the magn

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.

We have studied the stress dependence of the switching field in the glass-coated FeNbSiB microwire. The stress dependence can be tailored by properly choosing the frequency of exciting magnetic field. At low frequencies, the switching field is weakly

The devitrification of Finemet-based glass-coated microwires has been investigated by differential thermal analysis (DTA) and vibrating sample magnetometer (VSM). From the DTA, we have identified the crystallization of the non-magnetic phase during t
