 Recently there has been interest in exploring the coupling between magnets for use in information processing, however, this is hampered by the fact that such coupling is forbidden due to the different parity of the acoustic and optical magnets. Here, Comstock et al show that the interlayer Jialoshinsky-Maurier interaction in a layered hybrid antiferromagnet can allow for strong coupling between the acoustic and optical magnets, offering a pathway for magnon-coherent information processing.
