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…
Wide-range continuous tuning of the thermal conductivity of films via room-temperature ion-gel gating
Yingying Zhang, William M. Postiglione, Rui Xie +8
Solid-state control of the thermal conductivity of materials is of exceptional interest for novel devices such as thermal diodes and switches. Here, we demonstrate the ability to c…
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…
