Abstract: A magnetic device comprising at least a thin layer of a magnetisable material which shows an easy axis of magnetisation which extends approximately at right angles to the surface of the layer. Magnetic domains are produced, maintained and, if desireable, destroyed in the layer. A driving force is present for the transport of a domain. An alternating magnetic field having a frequency exceeding that of the driving force is produced at right angles to the plane of the thin layer as a result of which the transport of the domains is facilitated.

Abstract: A novel memory matrix and method of making same employing a support plate having formed therein recesses for receiving annular cores. The recesses include a group of conductive bars extending in each recess and above the plate surface. A group of circumscribing recesses are then provided, of a depth exceeding the core recesses but less than the plate thickness. Cores are then inserted into the recesses, and all recesses filled with an epoxy resin, up to slightly above the surface of the plate. The insulating surface is then printed with conductors interconnecting the ends of the bars as desired. The remaining metal on the other side of the support plate is then removed so that the circumscribed areas are electrically separated.
