Abstract

A switch for bubble propagation involves the use of a remote conductor 10, as shown in the drawing. The conductor 10 is located at a site that is remote to the switching site and the bubble path. A current in conductor 10, however, will change the magnetic state of the permalloy H-bar which, in turn, will influence the propagation path of the bubble.

H Bar Transfer Switch

A switch for bubble propagation involves the use of a remote conductor 10, as shown in the drawing. The conductor 10 is located at a site that is remote to the switching site and the bubble path. A current in conductor 10, however, will change the magnetic state of the permalloy H-bar which, in turn, will influence the propagation path of the bubble.

With no current in conductor 10, the bubble continues along path 1, 2, 3, 4 of the major loop. When a current is passed through the conductor 10, the bubble takes the path 1, 2, 3', 4' to transfer into the minor loop.

The conductor 10 may be replaced with bubbles to perform the switching function. This arrangement is also suitable for logic purposes.
