Observation of ice-rule violation and monopole dynamics via edge nucleation of domain walls in artificial spin ice lattice

In a patterned Co honeycomb spin ice structure, we show that violation in the ice-rule or magnetic monopoles, can be observed during a magnetization reversal process in 430 Oe≤H≤760 Oe magnetic field (H) range. The monopoles are shown to originate from the nucleation of domain walls at the edges, an...
