Thermal Conductivity and Magnetic Phase Diagram of CuB2O4
T. Kawamata, N. Sugawara, S. M. Haidar +11
We have measured temperature and magnetic field dependences of the thermal conductivity along the c-axis, kc, and that along the [110] direction, k110, of CuB2O4 single crystals in…
Nonmagnetic Impurity Effect of the S=1/2 Spin Ladder System (pipdH)_2Cu_{1-x}Zn_xBr_4
C. Yokoyama, E. Matsuoka, H. Sugawara +5
We report the synthesis and the magnetic susceptibility of (pipdH)2Cu1-xZnxBr4, which is a nonmagnetic impurity-doped S=1/2 spin ladder system. The samples were synthesized from a…
Anomalous Spin Dynamics observed by High Frequency ESR in Honeycomb Lattice Antiferromagnet InCu2/3V1/3O3
Susumu Okubo, Hideo Wada, Hitoshi Ohta +5
High-frequency ESR results on the S=1/2 Heisenberg hexagonal antiferromagnet InCu2/3V1/3O3 are reported. This compound appears to be a rare model substance for the honeycomb lattic…
Spin Configuration in the 1/3 Magnetization Plateau of Azurite Determined by NMR
F. Aimo, S. Kramer, M. Klanjsek +3
High magnetic field Cu NMR spectra were used to determine the local spin polarization in the 1/3 magnetization plateau of azurite, Cu(CO)(OH), which is a…
Quantum spin liquid states in the two dimensional kagome antiferromagnets, ZnxCu4-x(OD)6Cl2
S. -H. Lee, H. Kikuchi, Y. Qiu +4
A three-dimensional system of interacting spins typically develops static long-range order when it is cooled. If the spins are quantum (S = 1/2), however, novel quantum paramagneti…
