Abstract

We propose a formalism of a compact model for circuit simulations of spin wave interconnects. The developed SPICE Spin Wave model is based on the theory of numerical micromagnetics, and serves as a building block for a hierarchical circuit simulation tool for spintronic circuits and systems. We demonstrate excellent agreement between the SPICE model simulations and full micromagnetic solver results. We also present a scheme of exciting spin waves in spin wave bus having perpendicular magnetic anisotropy. Spin waves are excited with an oscillating change of magnetocrystalline anisotropy in a magnetoelectric cell. We use our proposed SPICE model to analyze this structure: determine the length of spin wave attenuation, delay in the bus, and the dependence of amplitude on the change of anisotropy.
