Popis:	The domain wall displacement in ferromagnetic crystals with dislocations that produce a continuous potential field with wavelength greater than the domain wall width is investigated by the machine modeling method. It is established that the domain wall shape and the start field are determined during magnetization by the potential field characteristics that depend on the specific location of the dislocations. It is shown that the start field is proportional to the ratio between the mean stress and the variance of the potential field stress at the site of domain wall fastening. The results of the modeling agree with values of the start field obtained experimentally and the behavior of the domain wall during magnetization of iron microcrystals.
