Abstract
The influence of Bloch lines on the relaxation of domain walls associa ted with the diffusion loss mechanism is revealed in garnet films usin g a dark-field magneto-optic technique. It is found that a shift of Bl och lines by an in-plane field leads to a jump of the domain wall osci llation amplitude which then restores anomalously slowly to its initia l value. The Slonczewski equations, modified to take into account diff usion terms, are analysed. The observed jump of the wall amplitude is explained by a change of the diffusion well due to a remagnetization o f domain walls by moving Bloch lines.
