Abstract: Interactions between single wall domains permit logic operations to be realized in magnetic sheets in which such domains are moved. Magnetically soft overlay patterns not only define propagation channels for such domains in response to magnetic fields reorienting in the plane of the sheet but also define channel intersections where logic functions are carried out. Domains are idled or, alternatively, in direction at those intersections depending on the positions of preceding domains. A variety of counter circuits are described.
