Abstract

A column propagation structure consists of an array of permalloy elements, one for each bubble in the lattice, overlaying a current conductor. An example of such a structure is shown in Fig. 1, where permalloy lattice confinement elements 10 are positioned next to chevron or C-bar propagation elements 12. A conductor 13 having a serpentine shape preferably is positioned so as to have a loop underlying each gap between the permalloy elements in the column.
