Popis:	When measuring the domain shrinking velocity of GdFeCo single layer film, which is an expanding layer of Magnetic AMplifying MO System (MAMMOS), scattering was seen in the shrinking velocity when the effective driving field was over 100 Oe. Walker's limit was thought of as the cause of the scattering, and then the damping constant was determined to be 0.29. When the in-plane field was applied, the scattering disappeared, and an increase in shrinking velocity was seen.
