ABSTRACT:
A replicator for a magnetic bubble domain device including a hairpin loop conductor element traversing first and second spaced apart bubble domain guide structures. The replicator functions to replicate a bubble domain travelling along the first bubble propagation path onto the second bubble propagation path in response to an activating signal on the conductor. The replicate guide structure includes two attractive cusp positions and one repulsive cusp position, so that the repulsive charged wall formed at the repulsive cusp position functions to sever a stretched bubble domain formed by the activating signal.
