The anhydrous divalent 3d-metal dirhenate quantum materials, M(ReO),were synthesized using solid-state methods for M = Mn through Zn. Previously unreported Mg(ReO4)2 is als…
Anomalous Thermal Conductivity Reversal Driven by a Fluctuating Charge Density Wave
Han Huang, Jinghang Dai, Joyce Christiansen-Salameh +14
For more than a century, the lattice thermal conductivity of crystalline solids has been known to decrease with increasing temperature, as the phonons that carry heat scatter more…
van der Waals Nanoreactors

Advancing the chemical synthesis of crystals is important for both fundamental research and practical applications of quantum materials. While established bulk-phase and thin-film…
Suppression of Intertwined Density Waves in LaNiCuO
Stephen Zhang, Danrui Ni, Ruyi Ke +3
Superconductivity in LaNiO has been reported to emerge upon suppression of intertwined spin and charge density wave (SDW/CDW) order, suggesting a possible connec…
Anisotropy of the zigzag order in the Kitaev honeycomb magnet -RuBr
John S. Pearce, David A. S. Kaib, Zeyu Ma +5
Kitaev materials often order magnetically at low temperatures due to the presence of non-Kitaev interactions. Torque magnetometry is a very sensitive technique for probing the magn…
Anisotropic magnetic interactions in a candidate Kitaev spin liquid close to a metal-insulator transition
Zeyu Ma, Danrui Ni, David A. S. Kaib +6
In the Kitaev honeycomb model, spins coupled by strongly-frustrated anisotropic interactions do not order at low temperature but instead form a quantum spin liquid with spin fracti…
