Geometric frustration and Dzyaloshinskii-Moriya interactions in a quantum star lattice hybrid copper sulfate
Hajime Ishikawa, Yuto Ishii, Takeshi Yajima +6
We study the magnetism of a layered, spin- organic-inorganic copper sulfate, which is a close realization of the star lattice antiferromagnet, one of the playgrounds of ge…
Rhenium oxyhalides: a showcase for anisotropic-triangular-lattice quantum antiferromagnets
M. Gen, D. Hirai, K. Morita +9
The spin-1/2 Heisenberg antiferromagnet on an anisotropic triangular lattice (ATL) is an archetypal spin system hosting exotic quantum magnetism and dimensional crossover. However,…
Superconductivity at 12 K in LaIOs: a 5d metal with osmium honeycomb layer
Hajime Ishikawa, Takeshi Yajima, Daisuke Nishio-Hamane +3
We discovered superconductivity at = 12 K in a layered compound LaIOs with osmium honeycomb network. Despite heavy constituent elements unfavorable for phonon mediate…
Spin-Peierls transition to a Haldane phase
Hironori Yamaguchi, Hiroki Takahashi, Takashi Kawakami +4
We present an organic compound exhibiting a spin-Peierls (SP) transition to an effective spin-1 antiferromagnetic uniform chain, that is, the Haldane chain. The clear disappearance…
Inelastic Neutron Scattering Study of the Spin Dynamics in the Breathing Pyrochlore System LiGa0.95In0.05Cr4O8
Yu Tanaka, Rafał Wawrzyńczak, Manh Duc Le +6
The A-site ordered chromate spinels LiGa1-xInxCr4O8 host a network of size-alternating spin-3/2 Cr3+ tetrahedra known as a 'breathing' pyrochlore lattice. For the x=0.05 compositio…
Emergence of nontrivial magnetic excitations in a spin liquid state of kagome volborthite
Daiki Watanabe, Kaori Sugii, Masaaki Shimozawa +7
When quantum fluctuations destroy underlying long-range ordered states, novel quantum states emerge. Spin-liquid (SL) states of frustrated quantum antiferromagnets, in which highly…
