Abstract :
Bubble propagation on several field access structures is studied with an optoelectrical method. Measurements were performed with a 40-Oe, 10-kHz rotating field on closed-loop shift registers that were fabricated on Bi-substituted garnet films having either 7 μm or 2.7 μm bubbles. The effect of increasing the interelement gap for several nonsymmetrical structures is discussed.
