Spin-Triplet Excitons in the Gapped Antiferromagnet BaCuSiO: Electron Paramagnetic Resonance Studies
S. A. Zvyagin, J. Wosnitza, J. Krzystek +4
BaCuSiO, a quantum antiferromagnet with a double-layer structure of Cu ions in a distorted planar-rectangular coordination and with a dimerized spin singlet…
Magnetic Field-Induced Condensation of Triplons in Han Purple Pigment BaCuSiO
M. Jaime, V. F. Correa, N. Harrison +9
Besides being an ancient pigment, BaCuSiO is a quasi-2D magnetic insulator with a gapped spin dimer ground state. The application of strong magnetic fields closes this gap…
Spin-Vacancy-Induced Long-Range Order in a New Haldane-Gap Antiferromagnet
Y. Uchiyama, Y. Sasago, I. Tsukada +5
Magnetic susceptibility, high-field magnetization and inelastic neutron scattering experiments are used to study the magnetic properties of a new S=1 quasi-1-dimensional antiferrom…
Large Thermopower in a Layered Oxide NaCo_2O_4
I. Terasaki, Y. Sasago, K. Uchinokura
A transition-metal oxide NaCo_2O_4 is a layered oxide in which CoO_2 and Na alternately stack along the c axis. Recently we have found that this compound shows unusually large ther…
BaCu_2Si_2O_7: a new quasi 1-dimensional S = 1/2 antiferromagnetic chain system
I. Tsukada, Y. Sasago, K. Uchinokura +5
The new antiferromagnetic (AF) compound BaCu_2Si_2O_7 is studied by magnetic susceptibility and neutron scattering techniques. The observed behavior is dominated by the presence of…
Similarity and Difference between Magnetic- and Nonmagnetic-Impurity Effects in Spin-Peierls Cuprate CuGeO_3
N. Koide, Y. Uchiyama, T. Hayashi +5
We have measured the magnetic susceptibility of single-crystal Cu_{1-x}Ni_xGeO_3 to study doping effects of the magnetic impurity (Ni^{2+} has S=1 spin) on the inorganic spin-Peier…
