Extending spin ice concepts to another geometry: the artificial triangular spin ice [PDF]

Physical Review B, 2012
In this work we propose and study a realization of an artificial spin ice-like system, not based on any real material, in a triangular geometry. At each vertex of the lattice, the "ice-like rule" dictates that three spins must point inward while the ...

Dynamics of magnetic charges in artificial spin ice [PDF]

Physical Review Letters, 2010
Artificial spin ice has been recently implemented in two-dimensional arrays of mesoscopic magnetic wires. We propose a theoretical model of magnetization dynamics in artificial spin ice under the action of an applied magnetic field.

Size distribution of magnetic charge domains in thermally activated but out-of-equilibrium artificial spin ice. [PDF]

Sci Rep, 2014
International audienceA crystal of emerging magnetic charges is expected in the phase diagram of the dipolar kagome spin ice. An observation of charge crystallites in thermally demagnetized artificial spin ice arrays has been recently reported by S ...

Field‐Induced Antiferromagnetic Correlations in a Nanopatterned Van der Waals Ferromagnet: A Potential Artificial Spin Ice [PDF]

Advanced Science
Nano‐patterned magnetic materials have opened new venues for the investigation of strongly correlated phenomena including artificial spin‐ice systems, geometric frustration, and magnetic monopoles, for technologically important applications such as ...

Thermodynamics of emergent magnetic charge screening in artificial spin ice [PDF]

Nature Communications, 2016
Inspired by the physics of bulk frustrated materials, arrays of coupled nanomagnets have been widely explored for the study of collective ordering and emergent behaviour.

Echo state property and memory capacity of artificial spin ice [PDF]

Scientific Reports
Physical reservoir computing by using artificial spin ice (ASI) has been proposed on the basis of both numerical and experimental analyses. ASI is a many-body system consisting of ferromagnets with various interactions.

Spin wave spectral probing of degenerate microstates in building-block of square artificial spin ice

AIP Advances, 2021
We have investigated the spin wave modes of dipolar coupled, highly shape anisotropic magnetic nanoislands forming square artificial spin ice system by performing micromagnetic simulations using MuMax3 in combination with Matlab coding.
