摘要： A non-volatile logic gate, including a magnetic material having a shape induced magnetic anisotropy, wherein a shape of the magnetic material has a first vertex, a second vertex, and a third vertex and supports a single magnetic domain; regions of the magnetic material including a first input region adjacent the first vertex, a second input region adjacent the second vertex, and an output region adjacent a third vertex; the first input region for receiving a first logic input to the logic gate, the second input region for receiving a second logic input to the logic gate, and the output region for outputting at least one logic output of the logic gate; and the shape induced magnetic anisotropy determining at least part of a truth table for the logic gate, so that the logic gate produces the at least one logic output from the logic inputs using the shape.
