Modeling interaction between Co/Pt nanomagnets and Permalloy domain wall for Nanomagnet Logic

摘要

Nanomagnet Logic (NML) emerges as one of the promising “beyond CMOS” computing architectures. Proposed NML devices require magnetic field clocking, generated by a power-hungry clocking structure. We recently proposed clocking nanomagnets with magnetic domain walls. This paper presents a combined experimental and computational study, exploring the interaction between Co/Pt nanomagnets and Permalloy domain walls. Our micromagnetic simulations verified the feasibility of achieving error-free antiferromagnetic ordering with the introduced clocking scheme.
