| Abstract | |
Artificial spin ices (ASIs) are designable arrays of interacting nanomagnets that span a wide range of magnetic phases. Here, we demonstrate that the phase of an artificial kagome spin ice can be identified through its initial magnetization curve. As a proof of concept, micromagnetic simulations of these curves were performed starting from representative microstates of different phases of the system. We show that the curves are characterized by phase-specific features in such a way that a supervised classification algorithm predicts the phase of the initial microstate with good reliability. Moreover, most curves associated with paramagnetic and spin ice 1 phases are recognizable simply by visual inspection. This achievement represents a different strategy for identifying phases in ASIs that is easier and more accessible than magnetic imaging techniques normally used for this task. (AU) | |
