摘要：
We studied the velocity of domain wall propagation, nu, of Fe69Si10B15C6 microwires with different metallic nucleus diameter, d, and different total diameter, D (d=14 mu m; D=33 mu m and d=18 mu m; D=23.4 mu m respectively) in the temperature range between 78 and 300 K and at different frequencies of applied magnetic field, nu(H) dependence is essentially not linear, showing significantly higher domain wall mobility, S=dv/dH, at low filed limit. All characteristics, nu(H) dependence, S(H) dependence and H-cr are sensitive to the sample geometry, i.e. to the internal stresses.
