Artificial spin ices are composed of a honeycomb lattice of nanoscale magnets. Depending on the orientation of the magnets in the lattice, the spin ice can host high or low effective magnetic charge at each vertex. Here, Guo et al use neutron spin echo spectroscopy to show that these magnetic charges exhibit sub-ns relaxation times, analogous to bulk spin-ices.
