spin wave
Spin waves, which are propagating collective excitations of magnetization precession, have attracted significant interest as next-generation information carriers because they enable data transmission without charge transport, achieving ultra-low-power operation. Although various spin-wave-based logic gates, such as NAND and majority gates, have been widely proposed, their functionalities remain limited to specific, hardwired logic operations.This study aims to realize parallel computing circuits capable of executing arbitrary unitary matrix operations by utilizing spin-wave transport in patterned magnetic channels. To establish design guidelines for such circuits, micromagnetic simulations were performed using MuMax3. Both perpendicularly magnetized and in-plane magnetized films were modeled to evaluate the transport characteristics of forward volume spin waves, which exhibit weak dependence on propagation direction and channel geometry.
