Magnons are excitations of magnetically ordered materials that correspond to spatial and temporal variations of the magnetic order parameter. In systems that spontaneously break rotational symmetry, these magnons are Nambu-Goldstone bosons, implying that, in the absence of long-range interactions, they should be gapped and, depending on the nature of the magnetic order parameter, should be either linearly or quadratically dispersing.
