摘要

Topological magnonics has attracted intense interest for application in energy efficient computational devices. Here, we show reconligurable magnonic band structure and band gap by a bias-field controlled spin texture in chains of connected Ni_(80)Fe_(20) submicron dots. Particularly for an identical field value, we achieve both "S" and shifted-core vortex states based on magnetic history leading to a drastic change in magnonic band structure. A first-order phase transition from the saturation to vortex state drives this change, as opposed to a continuous change from the saturation to S state.
