Title:
Magnetic ordering of focused-ion-beam structured Cobalt-Platinum dots for field-coupled computing
Abstract:
This paper presents an experimental and computational study of dipolar ordering phenomena in ion-beam patterned Co/Pt multilayers. The fabrication and the patterning of the layers were chosen to achieve single-domain dots, which show strong magnetic coupling and are uniform in their magnetic properties. We find that antiferromagnetic-like ordering can extend to as many as several hundred adjacent dots. Micromagnetic simulations reproduce the experimentally observed ordering and suggest that such multilayers are promising candidates for field-coupled computing devices. «
