Modern nanomagnetic devices involve materials and phenomena featuring both spin and charge transport. SPICE compatible spin circuits with 4-component voltage and current (1 for charge and 3 for spin) have been developed to represent this emerging class of devices. However there has not been much work on circuit representation for materials with high spin-orbit coupling (SOC) which are becoming increasingly important with the discovery of giant spin Hall effect (GSHE) and topological insulators.
