Controlling operation timing and data flow direction between nanomagnet logic elements with spatially uniform clock fields

We demonstrate a reliable method for controlling the operation timing and data flow direction in a nanomagnet logic (NML) circuit with spatially uniform magnetic fields. We introduce a data and buffer nanomagnet, which have the same shape, but their magnetic easy axes are at an angle of 45° to each other. We also introduce a ferromagnetically and an antiferromagnetically coupled arrangement of the nanomagnets. Using this method, we perform bit shift operations on 3-bit NML shift registers. This method provides a means of fabricating highly integrated NML circuits with a simplified structure.
