Magnonics, using spin-waves for information transmission and processing, offers a promising approach for low-power data processing. The challenge lies in controlling the local propagation path of spin-waves. In this study, writable magnonics is introduced by utilizing the reconfigurability and rewritability of artificial spin ice systems, enabling globally switchable spin-wave propagation and locally writable spin-wave nanochannels. This rewritable magnonics provides a unique platform for designing programmable magnonic circuits and logic devices for ultra-low power applications.
Magnonics, which employs spin-waves to transmit and process information, is a promising venue for low-power data processing. One of the major challenges is the local control of the spin-wave propagation path. Here, we introduce the concept of writable magnonics by taking advantage of the highly flexible reconfigurability and rewritability of artificial spin ice systems. Using micromagnetic simulations, we show that globally switchable spin-wave propagation and locally writable spin-wave nanochannels can be realized in a ferromagnetic thin film underlying an artificial pinwheel spin ice. The rewritable magnonics enabled by reconfigurable spin wave nanochannels provides a unique setting to design programmable magnonic circuits and logic devices for ultra-low power applications.
