Query: Artificial vertex systems by design   Arrays of interacting magnetic nanostructures were introduced recently as a
powerful approach to investigate experimentally the exotic many-body physics of
frustrated spin models. Following a similar strategy based on
lithographically-patterned magnetic lattices, we provide a first attempt to
fabricate a lab-on-chip platform to explore the physics of vertex models. The
central idea of this work is to replace the spin degree of freedom of
artificial frustrated spin systems by a local micromagnetic knob, which can be
finely tuned by a proper design of the vertex geometry. This concept is
demonstrated both numerically and experimentally on the celebrated six vertex
model, and we show how all variants of this model can be apprehended through
the engineering of magnetic square lattices. Our results open new avenues to
design arrays of magnetic nanostructures not only to study a wide range of
frustrated spin models, but to explore vertex models as well.
