GAPLESS DOUBLE-SIDED PROPAGATION STRUCTURE FOR BUBBLE DOMAIN DEVICES

摘要

Gapless, double-sided propagation structures are provided for implementing the continuous movement of magnetic bubble domains under the control of a reorienting in-plane field. Propagation is achieved by using two identical disc circuits on both sides of the bubble material displaced from each other by one-half of periodicity. The discs in each circuit are disposed in tangential engagement with each other and the two circuits may follow any desired path provided the circuits are in alignment with each other.
