Abstract

A magnetic domain propagation register carrying out the propagation of the domains under the effect of electric currents, comprising an insulating substrate, a soft magnetic layer on the insulating substrate, in which is formed a propagation channel, a hard magnetic layer on the soft magnetic layer, except in areas defining the propagation channel, an insulating layer on the soft and hard magnetic layers, and a conduction layer in a Greek border pattern on the insulating layer, constituted by parallel segments perpendicular to the propagation channel, the propagation channel comprising widened boxes at the intersection of the propagation channel with the segments of the conduction layer.
