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

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.
