Abstract: MAGNETIC BUBBLE Y-BAR CORNER A magnetic bubble Y-bar corner for use at the end of a minor loop. The Y-bar corner includes a Y-bar corner element and a canted I-bar positioned between the Y-bar corner element and each of the two adjacent storage elements in the minor loop. The ends of the arm of the Y-bar corner element are positioned adjacent the apex portions of the canted I-bars. The distance between the ends of the arms of the Y-bar is larger than the distance between the opposing ends of the two canted I-bars. With this corner a bubble propagates in either direction along a path from a minor loop storage element to the end of the canted I-bar and then to the apex portion of the canted I-bar and from there across to the end of the arm of the Y-bar.

Abstract: A rotating field access pattern for use in the propagation of a bubble lattice is disclosed. The pattern contains two sets of parallel oblong elements that are substantially perpendicular to each other. Four specific permalloy patterns featuring one element per one, two, two and four bubble domains are shown.
