Origin of oscillatory structures in the magnetothermal conductivity of the putative Kitaev magnet -RuCl
J. A. N. Bruin, R. R. Claus, Y. Matsumoto +6
The layered honeycomb magnet -RuCl has been suggested to exhibit a field-induced quantum spin liquid state, in which the reported large thermal Hall effect close to the half…
Multi-Center Magnon Excitations Open the Entire Brillouin Zone to Terahertz Magnetometry of Quantum Magnets
Tobias Biesner, Seulki Roh, Aleksandar Razpopov +14
Due to the small photon momentum, optical spectroscopy commonly probes magnetic excitations only at the center of the Brillouin zone; however, there are ways to override this restr…
Formation of orbital molecules on a pyrochlore lattice induced by A-O bond covalency
A. Krajewska, A. Yaresko, J. Nuss +15
The pyrochlore ruthenate InRuO displays a subtle competition between spin-orbital entanglement and molecular orbital formation. At room temperature, a spin-orbit-entang…
Nonmagnetic State and Spin-Orbit Excitations in KRuCl
H. Takahashi, H. Suzuki, J. Bertinshaw +10
Spin-orbit Mott insulators composed of transition metal ions may host excitonic magnetism due to the condensation of spin-orbital triplons. Prior experiments sugge…
Highly nonlinear magnetoelectric effect in antiferromagnetic Co4Ta2O9 single crystals
Nara Lee, Dong Gun Oh, Sungkyun Choi +10
Strongly correlated materials with multiple order parameters provide unique insights into the fundamental interactions in condensed matter systems and present opportunities for inn…
Spin waves and spin-state transitions in a ruthenate high-temperature antiferromagnet
H. Suzuki, H. Gretarsson, H. Ishikawa +16
Ruthenium compounds play prominent roles in materials research ranging from oxide electronics to catalysis, and serve as a platform for fundamental concepts such as spin-triplet su…
Magnetic properties of PdAs2O6: a dilute spin system with an unusually high Néel temperature
M. Reehuis, T. Saha-Dasgupta, D. Orosel +5
The crystal structure and magnetic ordering pattern of PdAs2O6 were investigated by neutron powder diffraction. While the magnetic structure of PdAs2O6 is identical to the one of i…
Spin exchange dominated by charge fluctuations of the Wigner lattice in the newly synthesized chain cuprate Na5Cu3O6
N. Zafar Ali, J. Sirker, J. Nuss +2
Na5Cu3O6, a new member of one dimensional charge ordered chain cuprates, was synthesized via the azide/nitrate route by reacting NaN3, NaNO3 and CuO. According to single crystal X-…
How chemistry controls electron localization in 3d1 perovskites: A Wannier-function study
E. Pavarini, A. Yamasaki, J. Nuss +1
In the series of 3d1 t2g perovskites, SrVO3--CaVO3--LaTiO3--YTiO3 the transition-metal d electron becomes increasingly localized and undergoes a Mott transition between CaVO3 and L…
