The elementary excitations of magnets are known as magnons. Like photons, they can carry information, but unlike photons, the interactions of magnons are intrinsically non-linear, making them particularly promising for physical reservoir computing, where the non-linear response of a dynamical system is used as a computational resource. Here, Körber et al demonstrate physical reservoir computing using the magnon eigenmodes of a permalloy disc.
