ABSTRACT:
Motion of a magnetic bubble material is caused by subjecting magnetic bubbles within the material to a magnetic field gradient. The bubbles respond to the magnetic field gradient by producing forces angled from the direction of the magnetic field gradient. The magnetic bubbles are constrained from moving within the magnetic bubble material, which is rotated in the magnetic field gradient to cause Bloch lines in bubble domain walls to rotate within the material. This produces forces causing the material to move.
