Abstract
Single-domain models are widely used for the approximate description of nanoscale magnetic switching. The goal of this article is to demonstrate them as a computationally efficient and physically established tool for the modeling and design of nanomagnetic logic (NML) devices. We introduce a systematic method for deriving single-domain parameters from numerical magnetic field calculations and investigate the validity of the single-domain description for lithographically fabricated nanomagnets in the sub-100-nm size range. We illustrate how a library of NML building blocks can be constructed and aid the design of complex circuitry. It will be demonstrated how single-domain models can be used to understand error formation in NML structures. The methods described here serve as a theoretical framework for a Simulation Program with Integrated Circuit Emphasis (SPICE)-like modeling tool for NML devices.
