Coupled spin-1/2 antiferromagnetic chain CsLiRuCl with partially disordered crystal lattice
Kazumitsu Watanabe, Nobuyuki Kurita, Hidekazu Tanaka +4
We determined the crystal structure of CsLiRuCl, which was synthesized first in this work, and investigated its magnetic properties. CsLiRuCl has a hexagonal struct…
Triplon band splitting and topologically protected edge states in the dimerized antiferromagnet
Kazuhiro Nawa, Kimihiko Tanaka, Nobuyuki Kurita +6
The search for topological insulators has been actively promoted in the field of condensed matter physics for further development in energy-efficient information transmission and p…
Quasi-two-dimensional Bose-Einstein condensation of spin triplets in dimerized quantum magnet BaCuSiOCl
Makiko Okada, Hidekazu Tanaka, Nobuyuki Kurita +9
We synthesized single crystals of composition BaCuSiOCl and investigated its quantum magnetic properties. The crystal structure is closely related to that of the qu…
Almost Perfect Frustration in the Dimer Magnet BaCoSiOCl
Hidekazu Tanaka, Nobuyuki Kurita, Makiko Okada +7
We determined the crystal structure of BaCoSiOCl, which was synthesized in this work, and investigated its quantum magnetic properties using single crystals. This c…
Partial ferromagnetic ordering and indirect exchange interaction in spatially anisotropic kagome antiferromagnet Cs_2Cu_3CeF_{12}
T. Amemiya, M. Yano, K. Morita +5
We report the crystal structure and unconventional magnetic ordering of Cs_2Cu_3CeF_{12}, which is composed of buckled kagome lattice of Cu^{2+} ions. The exchange network in the b…
Elementary excitations of S=1/2 one-dimensional antiferromagnet KCuGaF6 in magnetic field and quantum sine-Gordon model
Izumi Umegaki, Toshio Ono, Hidekazu Tanaka +2
Elementary excitations of the S=1/2 one-dimensional Heisenberg antiferromagnet KCuGaF with exchange constant =103 K were investigated by high-frequency ESR measurements…
