1. A structure comprising:
- a free FM layer disposed on a substrate;
a non-magnetic layer disposed on the free FM layer;
at least three input pillars disposed on the non-magnetic layer; and
an output pillar disposed on the non-magnetic layer,wherein each of the at least three input pillars and the output pillar comprise a first fixed FM layer disposed on the non-magnetic layer, an exchange layer disposed on the first fixed FM layer, and a second fixed FM layer disposed on the exchange layer, and a contact disposed on the second fixed FM layer.

Abstract
Methods of forming spin torque microelectronic devices are described. Those methods may include forming a free FM layer on a substrate, forming a non-magnetic layer on the free FM layer, forming at least three input pillars on the non-magnetic layer, and forming an output pillar on the non-magnetic layer to form a majority gate device.
