Efficient Dipole Coupled Nanomagnetic Logic in Stress Induced Elliptical Nanomagnet Array

Abstract

This letter presents an efficient dipole coupled nanomagnetic logic scheme clocked by voltage-induced stress. The logic signals can be transmitted to an array of eight elliptical nanomagnets in one cycle. Transmission speed is increased 1-2 times versus the conventional stress scheme while the required stress is reduced. Micromagnetic simulations illustrate that both increasing the tilt angleof the electrode pair and decreasing the nanomagnet thickness can reduce the stress. When the nanomagnet thickness is 8 to 12 nm and the tilt angle of the electrode pair is 8° to 10°, it is a tradeoff considering the stress, reliability, and fabrication.
