Abstract
The translational motion of magnetic bubble domains in a LuGdAlFe garnetfilm has been studied by high‐speed photography. It was found that the average bubble velocity during a field gradient pulse is strongly dependent on the pulse duration τ, varying from 4200 cm/sec at τ=100 nsec to 1700 cm/sec at τ=500 nsec, at a field difference across the bubble diameter of 9.3 Oe. Large overshoots were observed at τ=500 nsec, but were greatly reduced at τ=100 nsec.Keywords
