Field-coupled computing in magnetic multilayers

Abstract

This paper presents a computational study of ion-beam patterned cobalt-platinum multilayers, which could be used for field-coupled computing. We use micromagnetic simulations to reproduce measured hysteresis curves. This parameterized micromagnetic simulator then will be used for simulating interacting magnetic dots. We demonstrate how logic gates can be built from such coupled dots. We also show how electrical wires - placed beneath or above the magnetic dots - can provide a magnetic field, which propagates the magnetic signals. © Springer Science+Business Media LLC 2007.
