Nature of Magnetic Excitations in the High-Field Phase of -RuCl
A. N. Ponomaryov, L. Zviagina, J. Wosnitza +7
We present comprehensive electron spin resonance (ESR) studies of in-plane oriented single crystals of -RuCl, a quasi-two-dimensional material with honeycomb structure, focu…
Fantastic flat bands and where to find them: The CoSn-type compounds
William R. Meier, Mao-Hua Du, Satoshi Okamoto +6
Quantum interference on the kagome lattice generates electronic bands with narrow bandwidth, called flat bands. Crystal structures incorporating this lattice can host strong electr…
Field evolution of magnons in -RuCl by high-resolution polarized terahertz spectroscopy
Liang Wu, Arielle Little, Erik E. Aldape +13
The Kitaev quantum spin liquid (KSL) is a theoretically predicted state of matter whose fractionalized quasiparticles are distinct from bosonic magnons, the fundamental excitation…
Unconventional spin dynamics in the honeycomb-lattice material -RuCl: high-field ESR studies
A. N. Ponomaryov, E. Schulze, J. Wosnitza +8
We present high-field electron spin resonance (ESR) studies of the honeycomb-lattice material -RuCl, a prime candidate to exhibit Kitaev physics. Two modes of antiferromagne…
Antiferromagnetic resonance and terahertz continuum in RuCl
A. Little, Liang Wu, P. Lampen-Kelley +8
We report measurements of optical absorption in the zig-zag antiferromagnet -RuCl as a function of temperature, , magnetic field, , and photon energy, in the…
Destabilization of magnetic order in a dilute Kitaev spin liquid candidate
P. Lampen-Kelley, A. Banerjee, A. A. Aczel +6
The insulating honeycomb magnet -RuCl exhibits fractionalized excitiations that signal its proximity to a Kitaev quantum spin liquid (QSL) state, however, at , fragil…
Low-temperature crystal and magnetic structure of -RuCl3
H. B. Cao, A. Banerjee, J. -Q. Yan +6
Single crystals of the Kitaev spin-liquid candidate -RuCl have been studied to determine low-temperature bulk properties, structure and the magnetic ground state. Refinement…
Magnetic properties of the geometrically frustrated S=1/2 antiferromagnets, La2LiMoO6 and Ba2YMoO6, with the B-site ordered double perovskite structure: Evidence for a Collective Spin Singlet Ground State
T. Aharen, J. E. Greedan, A. A. Aczel +9
Two B-site ordered double perovskites, La2LiMoO6 and Ba2YMoO6, based on the S = 1/2 ion, Mo5+, have been investigated in the context of geometric magnetic frustration. Powder neutr…
