Deconstructing Magnetization Noise: Degeneracies, Phases, and Mobile Fractionalized Excitations in Tetris Artificial Spin Ice
M. Goryca, X. Zhang, J. Ramberger +5
Direct detection of spontaneous spin fluctuations, or "magnetization noise", is emerging as a powerful means of revealing and studying magnetic excitations in both natural and arti…
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-Induced Magnetic Monopole Plasma in Artificial Spin Ice
M. Goryca, X. Zhang, J. Li +6
Artificial spin ices (ASIs) are interacting arrays of lithographically-defined nanomagnets in which novel frustrated magnetic phases can be intentionally designed. A key emergent d…
String Phase in an Artificial Spin Ice
Xiaoyu Zhang, Ayhan Duzgun, Yuyang Lao +13
One-dimensional strings of local excitations are a fascinating feature of the physical behavior of strongly correlated topological quantum matter. Here we study strings of local ex…
Understanding Thermal Annealing of Artificial Spin Ice
Xiaoyu Zhang, Yuyang Lao, Joseph Sklenar +6
We have performed a detailed study of thermal annealing of the moment configuration in artificial spin ice. Permalloy (NiFe) artificial spin ice samples were examined…
Understanding magnetotransport signatures in networks of connected permalloy nanowires
Brian Le, Jungsik Park, Joseph Sklenar +8
The change in electrical resistance associated with the application of an external magnetic field is known as the magnetoresistance (MR). The measured MR is quite complex in the cl…
Self-assembled ErSb nanostructures of tunable shape and orientation: growth and plasmonic properties
Hong Lu, Daniel G. Ouellette, Sascha Preu +5
Self-assembled, semimetallic ErSb single crystal nanostructures, grown by molecular beam epitaxy, are embedded within a semiconductor GaSb matrix. Formation, evolution and orientat…
