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…

Crystal-Chemical Origins of the Ultrahigh Conductivity of Metallic Delafossites

Yi Zhang, Fred Tutt, Guy N. Evans +13

Despite their highly anisotropic complex-oxidic nature, certain delafossite compounds (e.g., PdCoO2, PtCoO2) are the most conductive oxides known, for reasons that remain poorly un…

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…

Ferroelectric quantum criticality and enhanced superconductivity in plastically deformed strontium titanate

S. Hameed, D. Pelc, Z. W. Anderson +13

The properties of quantum materials are commonly tuned using experimental variables such as pressure, magnetic field and doping. Here we explore a different approach: irreversible,…
