Abstract

The demonstration of NOT and OR logic gates using magnetic domain walls could suggest that digital circuit design methodology may apply directly to this new technology to build complex circuits. This paper shows that the use of an external rotating field which propagates domain walls of opposite magnetization in antiphase instants, reveals unforeseen delays which modify the operation of sequential logic circuits. To overcome this difficulty and to introduce a design methodology, a new device capable of re-synchronizing the signals is presented.
