Topological Kinetic Crossover in a Nanomagnet Array
Xiaoyu Zhang, Grant Fitez, Shayaan Subzwari +7
Ergodic kinetics, which are critical to equilibrium thermodynamics, can be constrained by a system's topology. We study a model nanomagnetic array in which such constraints visibly…
Collective ferromagnetism of artificial square spin ice
N. S. Bingham, X. Zhang, J. Ramberger +3
We have studied the temperature and magnetic field dependence of the total magnetic moment of large-area permalloy artificial square spin ice arrays. The temperature dependence and…
Magnetic-Field-Dependent Thermodynamic Properties of Square and Quadrupolar Artificial Spin Ice
M. Goryca, X. Zhang, J. D. Watts +4
Applied magnetic fields are an important tuning parameter for artificial spin ice (ASI) systems, as they can drive phase transitions between different magnetic ground states, or tu…
Entropy-driven order in an array of nanomagnets
Hilal Saglam, Ayhan Duzgun, Aikaterini Kargioti +14
Long-range ordering is typically associated with a decrease in entropy. Yet, it can also be driven by increasing entropy in certain special cases. We demonstrate that artificial sp…
Experimental Realization of the 1D Random Field Ising Model
N. S. Bingham, S. Rooke, J. Park +8
We have measured magnetic-field-induced avalanches in a square artificial spin ice array of interacting nanomagnets. Starting from the ground state ordered configuration, we imaged…
Field-tunable interactions and frustration in underlayer-mediated artificial spin ice
Susan Kempinger, Yu-Sheng Huang, Paul Lammert +5
Artificial spin ice systems have opened experimental windows into a range of model magnetic systems through the control of interactions among nanomagnet moments. This control has p…
