Reconfigurable spinwave dispersion in continuous magnetic layer induced via artificial spin ice based magnonic crystal

Spinwaves are a promising candidate for information processing in future computing technologies. Diodes and switches are routinely used in modern electronic circuitry and the hunt for spinwave equivalents is underway. Here we simulated a system which has many functionalities including anisotropic spinwave propagation, spinwave diode with frequency dependent propagation direction and the ability to prevent propagation. This is achieved by selecting the microstate of the reconfigurable artificial spin ice which is dipolar coupled to a continuous layer which supports spinwave propagation.
