Sažetak (engleski)

A recent model for the explanation of the decrease of coercive field H_c and the core loss E in amorphous ribbons carrying a direct current J_d has been extended in order to account for the effects of an alternating core current J. The model predicts a linear decrease of H_c with the amplitude J_0 of J and the achievement of H_c=0 for J_0 which is sufficient in order to release the domain walls responsible for H_c in the absence of the drive field H. The actual shape and frequency of the core current pulses appear to be immaterial as long as the condition J=J_0 at H = 0 is fulfilled. The accurate measurements performed on the stress-free Co_70.3Fe_4.7Si_15B_10 and twisted Fe_80B_20 ribbons confirm the validity of the model. Some applications of the phenomenon are briefly discussed.
