RELAXATION OF THE DYNAMIC DOMAIN WALLS ARISING DURING PULSATING REMAGNETIZATION OF THIN MAGNETIC FILMS IN WEAK FIELDS.

The structure of the dynamic domain walls which results from pulsating remagnetization of thin magnetic film from 500 to 1200 A thickness must be different from that of equilibrium walls. The range of thickness studied corresponds approximately to that in which there is an appreciable reduction in the mobility of domain walls. The decrease in mobility is attributed to a change in the structure of the equilibrium walls. Walls with cross ties are formed in this range, the appearance of the latter causing them to slow down further.
