Abstract

In this paper, we propose a prototype domain wall (DW) programmable magnetic logic device that is able to perform the AND and OR logic functions. The device operates by manipulating the information encoded in the internal spin structure of a transverse domain wall (TDW). The input and output bits in this scheme are the transverse profiles of the domain wall. By exploiting the inherent pinning and depinning mechanisms of the TDW within the device structure, the output DW profile can be deterministically controlled. The logical operation can be programmed at run time by the application of a local Oersted field.
