Thermal Phase Transitions in Artificial Spin Ice [PDF]
Physical Review Letters, 2013 We use the sixteen vertex model to describe bi-dimensional artificial spin ice (ASI). We find excellent agreement between vertex densities in fifteen differently grown samples and the predictions of the model. Our results demonstrate that the samples are in usual thermal equilibrium away from a critical point separating a disordered and an anti ...

MAGNETIZATION DYNAMICS IN A MODIFIED SQUARE ARTIFICIAL SPIN ICE [PDF]
, 2022 Artificial spin ices are magnetic metamaterials consisting of nanomagnet arrays in a 2-D lattice. Typically, these nanomagnet arrays are binary macrospins that can only be in an up or down state similar to the Ising spins. They have been intensively used

Emergent magnetic monopole dynamics in macroscopically degenerate artificial spin ice. [PDF]
Sci Adv, 2019 Magnetic monopoles, proposed as elementary particles that act as isolated magnetic south and north poles, have long attracted research interest as magnetic analogs to electric charge.

Temperature-dependent collective magnetization reversal in a network of ferromagnetic nanowires
AIP Advances, 2021 The collective behavior of geometrically frustrated magnetization in connected networks of ferromagnetic nanowires, known as artificial spin ice, leads to complex magnetotransport behavior in those structures.

Modal Frustration and Periodicity Breaking in Artificial Spin Ice [PDF]
Small, 2020 AbstractHere, an artificial spin ice lattice is introduced that exhibits unique Ising and non‐Ising behavior under specific field switching protocols because of the inclusion of coupled nanomagnets into the unit cell. In the Ising regime, a magnetic switching mechanism that generates a uni‐ or bimodal distribution of states dependent on the alignment ...

Direct observation of the ice rule in an artificial kagome spin ice [PDF]
Physical Review B, 2008 Recently, significant interest has emerged in fabricated systems that mimic the behavior of geometrically-frustrated materials. We present the full realization of such an artificial spin ice system on a two-dimensional kagome lattice and demonstrate rigid adherence to the local ice rule by directly counting individual pseudo-spins.

Unhappy vertices in artificial spin ice: new degeneracies from vertex frustration
New Journal of Physics, 2013 In 1935, Pauling estimated the residual entropy of water ice with remarkable accuracy by considering the degeneracy of the ice rule solely at the vertex level . Indeed, his estimate works well for both the three-dimensional pyrochlore lattice and the two-
