Nanomagnet logic (NML) emerges as a new field of spintronics. For NML operation, strong external magnetic clocking field pulses are required. The power-efficient generation of such fields is a challenge for magnetic computing. The idea of clocking Co/Pt nanomagnets with stray field from the domain wall of a Permalloy stripe was proposed in the earlier study. Here, we present a micromagnetic investigation of Co/Pt multilayer films that strongly interact with the stray field of a Permalloy domain wall conductor. The simulated domain patterns agree well with experimental results. © 2012 IEEE.
