Evidence for a Field-Induced Quantum Spin Liquid in α - RuCl 3
Seung-Ho Baek,Seung-Hwan Do,K.-Y. Choi,Y. S. Kwon,A. U. B. Wolter,Satoshi Nishimoto,Jeroen van den Brink,Bernd Büchner +7 more
TL;DR: These results provide direct evidence that α-RuCl_{3} exhibits a magnetic-field-induced QSL, and exclude that the ground state is a fully polarized ferromagnet.
Journal ArticleDOI
Spin-orbital separation in the quasi-one-dimensional Mott insulator Sr2CuO3.
J. Schlappa,J. Schlappa,Krzysztof Wohlfeld,K.J. Zhou,K.J. Zhou,Martin Mourigal,Maurits W. Haverkort,Vladimir N. Strocov,Liviu Hozoi,Claude Monney,Satoshi Nishimoto,Surjeet Singh,Surjeet Singh,A. Revcolevschi,Jean-Sébastien Caux,L. Patthey,Henrik M. Rønnow,J.E. van den Brink,T. Schmitt +18 more
TL;DR: The separation of the orbital degree of freedom (orbiton) is observed using resonant inelastic X-ray scattering on the one-dimensional Mott insulator Sr2CuO3 to resolve an orbiton separating itself from spinons and propagating through the lattice as a distinct quasi-particle with a substantial dispersion in energy over momentum.
Journal ArticleDOI
Kitaev exchange and field-induced quantum spin-liquid states in honeycomb α -RuCl 3
Ravi Yadav,Nikolay A. Bogdanov,Vamshi M. Katukuri,Satoshi Nishimoto,Jeroen van den Brink,Jeroen van den Brink,Liviu Hozoi +6 more
TL;DR: In this paper, it was shown that the Kitaev interaction is ferromagnetic, as in 5d5 iridium honeycomb oxides, and indeed defines the largest superexchange energy scale.
Journal ArticleDOI
Kitaev interactions between j = 1/2 moments in honeycomb Na2IrO3 are large and ferromagnetic: insights from ab initio quantum chemistry calculations
Vamshi M. Katukuri,Satoshi Nishimoto,Viktor Yushankhai,Viktor Yushankhai,A. Stoyanova,Hem C. Kandpal,Sungkyun Choi,Radu Coldea,Ioannis Rousochatzakis,Liviu Hozoi,Jeroen van den Brink +10 more
TL;DR: In this article, the results of ab initio many-body electronic-structure calculations and establish that the nearest-neighbor exchange is strongly anisotropic with a dominant ferromagnetic Kitaev part, whereas the Heisenberg contribution is significantly weaker and antiferromagnetic.
Journal ArticleDOI
Spin-orbit excitation energies, anisotropic exchange, and magnetic phases of honeycomb RuCl3
Ravi Yadav,Nikolay A. Bogdanov,Vamshi M. Katukuri,Satoshi Nishimoto,Jeroen van den Brink,Liviu Hozoi +5 more
TL;DR: The promise for spin-liquid behavior in the 4d5 honeycomb halide α-RuCl3 is discussed, and indications for a transition from zigzag order to a gapped spin liquid when applying magnetic field are found.
