Multiple Spin-Orbit Excitons and the Electronic Structure of -RuCl
P. Warzanowski, N. Borgwardt, K. Hopfer +7
The honeycomb compound -RuCl is widely discussed as a proximate Kitaev spin-liquid material. This scenario builds on spin-orbit entangled moments arising for a $t_…
Enhancement of magnetodielectric coupling in 6H-perovskites Ba3RRu2O9 for heavier rare earth cations (R=Ho,Tb)
Tathamay Basu, Vincent Caignaert, Somnath Ghara +5
The role of rare-earth (R) ions on the magnetodielectric (MD) coupling is always intriguing and markedly different for different systems. Although many reports are available concer…
Johari-Goldstein relaxation in glass-electrets
P. Lunkenheimer, F. Humann, D. Reuter +3
We investigate the dielectric response in the glass-electret state of two dipolar glass-forming materials. This unusual polar glassy state of matter is produced when a dipolar liqu…
High-Field Quantum Disordered State in -RuCl3: Spin Flips, Bound States, and a Multi-Particle Continuum
A. Sahasrabudhe, D. A. S. Kaib, S. Reschke +15
Layered -RuCl3 has been discussed as a proximate Kitaev spin liquid compound. Raman and THz spectroscopy of magnetic excitations confirm that the low-temperature antiferromagnet…
Plastic-crystalline solid-state electrolytes: Ionic conductivity and orientational dynamics in nitrile mixtures
D. Reuter, P. Lunkenheimer, A. Loidl
Many plastic crystals, molecular solids with long-range, center-of-mass crystalline order but dynamic disorder of the molecular orientations, are known to exhibit exceptionally hig…
Spin relaxation in CsCuClBr
R. Hassan Abadi, R. M. Eremina, M. Hemmida +5
The quantum-spin S = 1=2 chain system CsCuCl is of high interest due to competing anti-ferromagnetic intra-chain J and inter-chain exchange J' interactions and represents a…
