ABSTRACT:
An improved magnetic domain generator for a magnetic arrangement employing a layer of garnet in which single wall domains (bubbles) are moved by an in-plane rotating magnetic field. A first domain generator includes a first propagation circuit for moving bubbles away from the generator when the rotating field is in a first direction. A second domain generator includes a second propagation circuit for moving bubbles away from the second generator when the rotating magnetic field is in an opposite direction to the first direction. The two generators are coupled to a common pulse source which is able to provide pulses at twice the rate of rotation of the magnetic field. In this manner, two independent streams of bubbles may be produced by the generators from a single pulse source.
