Patent ID: 8058906

Claim:
A non-majority magnetic logic gate device comprising a substrate; a plurality of symmetrically aligned magnetic islands (SAMIs) disposed on the substrate, wherein most of the SAMIs are disposed either substantially perpendicular or substantially in parallel relative to a sweeping direction of an applied magnetic clock field such that the applied magnetic clock field is applied substantially parallel or perpendicular to a plane of the substrate; most of the SAMIs having a length longer than a width that respectively define easy and hard magnetic axes, most of the SAMIs are electrically isolated from each other, those SAMIs that are symmetrically aligned lengthwise side by side next to each other tend towards exhibiting antiferromagnetic coupling with each other, and those SAMIs that are symmetrically aligned widthwise side by side next to each other tend towards exhibiting ferromagnetic coupling with each other; a misaligned magnetic island (MAMI) disposed on the substrate wherein the MAMI having a length longer than a width that respectively define easy and hard magnetic axes, the MAMI is electrically isolated from the SAMIs, the MAMI magnetically coupled and sandwiched in between two SAMIs, and the MAMI exhibiting a magnetization ground state bias which is dependent upon the sweeping direction of the applied magnetic clock field; a plurality of magnetic field inputs (MFIs) disposed on the substrate and magnetically coupled to some of the SAMIs; and a magnetic field output (MFO) disposed on the substrate and magnetically coupled to the MAMI.
