Weak-coupling to strong-coupling quantum criticality crossover in a Kitaev quantum spin liquid -RuCl
Jae-Ho Han, Seung-Hwan Do, Kwang-Yong Choi +5
We report an unprecedented quantum criticality crossover representing two different universal scaling behaviors in a Kitaev quantum magnetic material -RuCl. -RuCl pre…
Putative spin liquid in the triangle-based iridate BaIrTiO
W. -J. Lee, S. -H. Do, Sungwon Yoon +10
We report on thermodynamic, magnetization, and muon spin relaxation measurements of the strong spin-orbit coupled iridate BaIrTiO, which constitutes a new frustration m…
Incarnation of Majorana Fermions in Kitaev Quantum Spin Lattice
Seung-Hwan Do, Sang-Youn Park, Junki Yoshitake +10
Kitaev quantum spin liquid is a topological magnetic quantum state characterized by Majorana fermions of fractionalized spin excitations, which are identical to their own antiparti…
Glassy Spin Freezing and Gapless Spin Dynamics in a Spatially Anisotropic Triangular Antiferromagnet Ag2MnO2
S. Ji, J. -H. Kim, Y. Qiu +6
Using elastic and inelastic neutron scattering techniques, we show that upon cooling a spatially anisotropic triangular antiferromagnet AgMnO freezes below K…
Weakly coupled quantum spin singlets in BaCrO
M. Kofu, J. -H. Kim, S. Ji +6
Using single crystal inelastic neutron scattering with and without application of an external magnetic field and powder neutron diffraction, we have characterized magnetic interact…
