Effective Temperature in an Interacting Vertex System: Theory and Experiment on Artificial Spin Ice
Effective Temperature in an Interacting Vertex System: Theory and Experiment on Artificial Spin Ice
Frustrated arrays of interacting single-domain nanomagnets provide important model systems for statistical mechanics, because they map closely onto well-studied vertex models and are amenable to direct imaging and custom engineering. Although these systems are manifestly athermal, we demonstrate that the statistical properties of both hexagonal and square lattices can be …
