Behavior of the breathing pyrochlore lattice BaYbZnO in applied magnetic field
J. G. Rau, L. S. Wu, A. F. May +9
The breathing pyrochlore lattice material BaYbZnO exists in the nearly decoupled limit, in contrast to most other well-studied breathing pyrochlore compounds. As…
Frustrated quantum rare-earth pyrochlores
Jeffrey G. Rau, Michel J. P. Gingras
In this review we provide an introduction to the physics of a series of frustrated quantum rare-earth pyrochlores. We first give a background on the microscopic single- and two-ion…
Quantum and Classical Phases of the Pyrochlore Heisenberg Model with Competing Interactions
Yasir Iqbal, Tobias Müller, Pratyay Ghosh +5
We investigate the quantum Heisenberg model on the pyrochlore lattice for a generic spin in the presence of nearest-neighbor and second-nearest-neighbor exchang…
From mean-field localized magnetism to itinerant spin fluctuations in the "Non-metallic metal" - FeCrAs
K. W. Plumb, C. Stock, J. A. Rodriguez-Rivera +6
FeCrAs displays an unusual electrical response that is neither metallic in character nor divergent at low temperatures, as expected for an insulating response, and therefore it has…
