Magnon Accumulation in Chirally Coupled Magnets (1909.00953v1)
Published 3 Sep 2019 in cond-mat.mtrl-sci and cond-mat.mes-hall
Abstract: We report strong chiral coupling between magnons and photons in microwave waveguides that contain chains of small magnets on special lines. Large magnon accumulations at one edge of the chain emerge when exciting the magnets by a phased antenna array. This mechanism holds the promise of new functionalities in non-linear and quantum magnonics.
