Abstract: Magnetic crystals have been found capable of structuring themselves into information channels under certain magnetic conditions. A propagation mechanism for moving magnetic domains, such as bubbles, along channels so defined has been discovered also. The dimensions of the channel and the size of the bubbles movable along the channel depend on material properties rather than on photolithographic resolution. Thus, the necessity for photolithographic processing previously employed for defining the familiar bubble movement implementations is eliminated, and both packing densities and yields are expected to be extremely high.

Abstract: Layers of materials in which single wall domains can be moved and operated in the familiar field access mode are organized in an array and operated in a word-organized block access fashion which permits an advantageous noise cancellation detection arrangement.
