“…Such a value corresponds well to the one found in [9,11]. Different temperature dependence than Co 68 Mn 7 Si 15 B 10 microwire could be explained by the different pinning mechanism in the both samples (compare H sw $ f(T) given in Fig.…”

“…In contrary to Co 68 Mn 7 Si 15 B 10 microwire, where strong temperature dependence of b was found [9], the power exponent b is almost constant in whole temperature range, having the value of 0.32-0.35. Such a value corresponds well to the one found in [9,11].…”

“…Results previously reported, showed that the DW can propagate below the switching field or even with a negative H 0 [12,13]. On the other hand, it has been already verified that at low applied fields the DW dynamics can be well described by a power-law [14,15] as…”

“…For low applied fields, a clear power-law behavior is observed, showing that the DW dynamics is in the adiabatic regime. The v Â H data, for fields below 5 Oe, of all samples and applied axial stress were fitted to the expression in an adiabatic regime [15]. However, some few variations on the b can be identified as a function of both, applied stress and Joule annealing.…”

a b s t r a c tIn this work, we determine the domain wall velocity in the low field region and study the domain dynamics in as-cast and annealed bi-stable amorphous glass-covered Fe 77.5 Si 7.5 B 15 microwires. In particular, from the relation between the domain wall velocity and magnetic field in the adiabatic regime, the power-law critical exponent b, the critical field H 0 and the domain wall damping Z were obtained. It has been verified that the main source of domain wall damping is the eddy current and spin relaxation, both with a strong relation with the magnetoelastic energy. This energy term is changed by the axial applied stress, which, by its time, modifies the damping mechanisms. It was also verified that the domain wall damping terms present different behavior at low (mainly eddy currents) and high applied stress (spin relaxation).

“…Velocity of this domain wall can be very high and so this phenomenon can be very interesting for technical applications. On the other hand the study of a single domain wall dynamics can give important information for understanding the process of magnetization reversal [4][5][6][7][8] and about dynamic characteristics of a single domain wall [9,10].…”
