The effect of the size of the system, aspect ratio and impurities concentration on the dynamic of emergent magnetic monopoles in artificial spin ice systems
In this work we study the dynamical properties of a finite array of
nanomagnets in artificial kagome spin ice at room temperature. The dynamic
response of the array of nanomagnets is studied by implementing a "frustrated
celular aut\'omata" (FCA), based in the charge model and dipolar model. The FCA
simulations, allow us to study in real-time and deterministic way, the dynamic
of the system, with minimal computational resource. The update function is
defined according to the coordination number of vertices in the system. Our
results show that for a set geometric parameters of the array of nanomagnets,
the system exhibits high density of Dirac strings and high density emergent
magnetic monopoles. A study of the effect of disorder in the arrangement of
nanomagnets is incorporated in this work
