Topotactically induced oxygen vacancy order in nickelate single crystals
Yu-Mi Wu, Pascal Puphal, Hangoo Lee +6
The strong structure-property coupling in rare-earth nickelates has spurred the realization of new quantum phases in rapid succession. Recently, topotactic transformations have pro…
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…
Topotactic transformation of single-crystals: from perovskite to infinite-layer nickelates
Pascal Puphal, Yu-Mi Wu, Katrin Fürsich +9
Topotactic transformations between related crystal structures are a powerful emerging route for the synthesis of novel quantum materials. Whereas most such "soft chemistry" experim…
