Sub-tesla on-chip nanomagnetic metamaterial platform for angle-resolved photoemission spectroscopy
Wenxin Li, Wisha Wanichwecharungruang, Mingyang Guo +14
Magnetically controlled states in quantum materials are central to their unique electronic and magnetic properties. However, direct momentum-resolved visualization of these states…
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…
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…
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…
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…
