Abstract: This paper reports a theoretical design that is a conceptual step forward; spin accumulation is used as the basis of a semiconductor computer circuit rather than flow of spin. A logic gate in this design consists of five magnetic leads on top of a semiconductor layer and is found to perform fast logic operations. The idea is further developed by demonstrating the capability to interconnect a large number of gates.
