Chiral Magnonic Resonators: Rediscovering the Basic Magnetic Chirality in Magnonics
arXiv:2111.01508 · doi:10.1063/5.0068820
Abstract
The outlook for producing useful practical devices within the paradigm of magnonics rests on our ability to emit, control and detect coherent exchange spin waves on the nanoscale. Here, we argue that all these key functionalities can be delivered by chiral magnonic resonators - soft magnetic elements chirally coupled, via magneto-dipole interaction, to magnonic media nearby. Starting from the basic principles of chiral coupling, we outline how they could be used to construct devices and explore underpinning physics, ranging from basic logic gates to field programmable gate arrays, in-memory computing, and artificial neural networks, and extending from one- to two- and three-dimensional architectures.
