Abstract:

We propose and analyze the feasibility of logic circuits utilizing spin waves as a physical mechanism for information transmission and processing. The novelty of this approach is that information transmission is accomplished without charge transfer. The performance of the proposed logic circuit is illustrated by numerical modeling based on the available experimental data for spin wave excitation and propagation in NiFe film. Logic circuits with the spin wave bus may be beneficial in reducing power consumption and subsequently resolve the interconnection problem. Another anticipated benefit is in the enhanced logic functionality. The shortcomings and limitations of the spin wave bus are discussed.
