Magnetic structure and high-field magnetization of the distorted kagome lattice antiferromagnet CsCuSnF
K. Matan, T. Ono, G. Gitgeatpong +12
High-resolution time-of-flight powder neutron diffraction and high-field magnetization were measured to investigate the magnetic structure and existence of a field-induced magnetic…
Elementary excitations and specific heat in quantum sine-Gordon spin chain KCuGaF6
I. Umegaki, T. Ono, H. Tanaka +2
Elementary excitations of an S = 1/2 antiferromagnetic Heisenberg chain KCuGaF6 were investigated through specific heat and electron spin resonance (ESR) measurements. In this comp…
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…
Orbital Configurations and Magnetic Properties of Double-Layered Antiferromagnet CsCuClBr
F. Yamada, T. Ono, H. Tanaka +1
We report the single-crystal X-ray analysis and magnetic properties of a new double-layered perovskite antiferromagnet, CsCuClBr. This structure is composed of Cu$_…
Magentic-Field Induced Quantum Phase Transition and Critical Behavior in a Gapped Spin System TlCuCl
F. Yamada, T. Ono, M. Fujisawa +2
Magnetization measurements were performed on TlCuCl with gapped ground state. The critical density and the magnetic phase diagram were obtained. The interacting constant was ob…
Magnetic Phase Transition and Magnetization Plateau in CsCuBr
H. Tanaka, T. Ono, H. A. Katori +3
The crystal structure of CsCuBr is the same as that of CsCuCl, which has been characterized as a spin-1/2 quasi-two-dimensional frustrated system. The magnetic prop…
Impurity-Induced Antiferromagnetic Ordering in the Spin Gap System TlCuCl_3
A. Oosawa, T. Ono, H. Tanaka
The magnetization measurements have been performed on the doped spin gap system TlCu_{1-x}Mg_xCl_3 with x <= 0.025. The parent compound TlCuCl_3 is a three-dimensional coupled spin…
Field-Induced Two-Step Phase Transitions in the Singlet Ground State Triangular Antiferromagnet CsFeBr
Y. Tanaka, H. Tanaka, T. Ono +7
The ground state of the stacked triangular antiferromagnet CsFeBr is a spin singlet due to the large single ion anisotropy . The field-induced magnetic ordering in th…
