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…
