| Popis: | Spin Wave (SW) has attracted great interest as information carrier in the past decades. Information transmission and processing between devices is achieved by collective precessional motion of magnetization without charge transfer, which enables lower energy consumption. In this paper, we perform several micromagnetic simulations to excite propagating spin wave and find that smaller external magnetic field can excite spin wave with shorter wavelength. A proper external magnetic(1800–2000mT) can excite spin wave with strong intensity for long-distance propagation. These findings will provide guideline in spin wave based logic devices design. |
