Thin-magnetic-film general-purpose uniform array based on controlled domain motion

Thin-film uniform arrays (UA´s) are general purpose, easy to produce, and reliable even when implementing complex logic functions. The use of controlled domain motion in narrow channels of low coercive force, formed in a high-coercive-force film, may serve as the basis for the implementation of large uniform programmable logic arrays with memory which feature information storage immune to power supply failures, and the simplicity of logic and control implementation. In this paper, principles of UA design are considered. Attention is given to performing logic operations using the controllable movement of magnetic domains in thin films.
