High-frequency dynamics in artificial spin ice [PDF]

open access: yes, 2019
High-frequency techniques such as ferromagnetic resonance measurements are a sensitive probe of how internal magnetic fields are distributed in ferromagnetic samples and as such may be used to gain information about the magnetic state of complex systems.

Thermal relaxation and ground state ordering in artificial spin ice [PDF]

open access: yes, 2014
We have studied the thermal relaxation of artifcial spin ice in its two main geometries, namely artificial square ice and artificial kagome spin ice.

Artificial Kagome Spin Ice [PDF]

open access: yes, 2008
Geometrical frustration is known to significantly modify the properties of many materials. Pyrochlore spin ice and hexagonal water ice are canonical systems that show the effects of frustration in both heat capacity and dynamical response.

Crystalline phases and devil's staircase in qubit spin ice

open access: yesPhysical Review Research, 2023
Motivated by the recent realization of an artificial quantum spin ice in an array of superconducting qubits with tunable parameters [King et al., Science 373, 576 (2021)0036-807510.1126/science.abe2824], we scrutinize a quantum six-vertex model on the ...

Evolving Artificial Spin Ice for Robust Computation [PDF]

open access: yes, 2023
Artificial spin ice is a magnetic metamaterial showing particular promise as a novel substrate for unconventional computing. While simulations are invaluable for investigating new computational substrates, results must be robust to the noise and disorder

Avalanches and disorder-induced criticality in artificial spin ices

open access: yesNew Journal of Physics, 2014
We show that both square and kagome artificial spin ice systems exhibit disorder-induced nonequilibrium phase transitions, with power law avalanche distributions at the critical disorder level.

Quenched dynamics of artificial colloidal spin ice

open access: yesPhysical Review Research, 2020
Artificial spin ices are ideal frustrated model systems in which to explore or design emergent phenomena with unprecedented characterization of the constituent degrees of freedom. In square spin ice, violations of the ice rule are topological excitations

Chiral switching and dynamic barrier reductions in artificial square ice

open access: yesNew Journal of Physics, 2021
Collective dynamics in lithographically-defined artificial spin ices offer profound insights into emergent correlations and phase transitions of geometrically-frustrated Ising spin systems.

Magnetic and electrical transport properties of artificial spin ice [PDF]

open access: yes, 2014
This thesis explores the mechanisms of the magnetic reversal of permalloy artificial spin ice arrays. The main research foci include the influence of domain wall propagation on the magnetic reversal of honeycomb artificial spin ice, the low temperature

Dynamics of reconfigurable artificial spin ice: Toward magnonic functional materials

open access: yesAPL Materials, 2020
Over the past few years, the study of magnetization dynamics in artificial spin ices has become a vibrant field of study. Artificial spin ices are ensembles of geometrically arranged, interacting magnetic nanoislands, which display frustration by design.
