Neutron scattering and muon-spin spectroscopy studies of the magnetic triangular-lattice compounds LaNiWO ( = Sr, Ba)
B. C. Yu, J. Y. Yang, D. J. Gawryluk +4
We report on the geometrically frustrated two-dimensional triangular-lattice magnets LaNiWO ( = Sr, Ba) studied mostly by means of neutron powder diffraction…
Quantum Critical Magnetic Excitations in Spin-1/2 and Spin-1 Chain Systems
Y. Xu, L. S. Wang, Y. Y. Huang +9
The study of CoNbO sits at the confluence of simplicity and complexity: on one hand, the model for Ising chains -- the building blocks of CoNbO -- in a transverse f…
Heat Transport in Herbertsmithite: Can a Quantum Spin Liquid Survive Disorder?
Y. Y. Huang, Y. Xu, Le Wang +10
Arguably the most favorable situation for spins to enter the long-sought quantum spin liquid (QSL) state is when they sit on a kagome lattice. No consensus has been reached in theo…
Anomalous Hall resistivity and possible topological Hall effect in the EuAl antiferromagnet
T. Shang, Y. Xu, D. J. Gawryluk +4
We report the observation of anomalous Hall resistivity in single crystals of EuAl, a centrosymmetric tetragonal compound, which exhibits coexisting antiferromagnetic (AFM) and…
Unconventional transverse transport above and below the magnetic transition temperature in Weyl semimetal EuCdAs
Y. Xu, L. Das, J. Z. Ma +10
As exemplified by the growing interest in the quantum anomalous Hall effect, the research on topology as an organizing principle of quantum matter is greatly enriched from the inte…
Magnetotransport of dirty-limit van Hove singularity quasiparticles
Yang Xu, František Herman, Veronica Granata +13
Tuning of electronic density-of-states singularities is a common route to unconventional metal physics. Conceptually, van Hove singularities are realized only in clean two-dimensio…
Multiple- to single-gap superconductivity crossover in NbIrPtO alloys
Y. Xu, S. Jöhr, L. Das +5
By using mostly the muon-spin rotation/relaxation (SR) technique, we investigate the superconductivity (SC) of NbIrPtO ( and 1.6) alloys, with $T_c = 10.5…
Electronic reconstruction forming a -symmetric Dirac semimetal in CaRuO
M. Horio, Q. Wang, V. Granata +19
Electronic band structures in solids stem from a periodic potential reflecting the structure of either the crystal lattice or an electronic order. In the stoichiometric ruthenate C…
