High-temperature magnetostructural transition in van der Waals-layered a-MoCl3
Michael A. McGuire, Jiaqiang Yan, Paula Lampen-Kelley +9
The crystallographic and magnetic properties of the cleavable 4d3 transition metal compound a-MoCl3 are reported, with a focus on the behavior above room temperature. Crystals were…
Excitations in the field-induced quantum spin liquid state of alpha-RuCl3
A. Banerjee, P. Lampen-Kelley, J. Knolle +14
The Kitaev model on a honeycomb lattice predicts a paradigmatic quantum spin liquid (QSL) exhibiting Majorana Fermion excitations. The insight that Kitaev physics might be realized…
Magnetic order and interactions in ferrimagnetic Mn3Si2Te6
Andrew F. May, Yaohua Liu, Stuart Calder +6
The magnetism in MnSiTe has been investigated using thermodynamic measurements, first principles calculations, neutron diffraction and diffuse neutron scattering on sin…
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…
Discovery of Log-Periodic Oscillations in Ultra-Quantum Topological Materials
Huichao Wang, Haiwen Liu, Yanan Li +10
Quantum oscillations are usually the manifestation of the underlying physical nature in condensed matter systems. Here we report a new type of log-periodic quantum oscillations in…
