Reentrant Spin-Peierls Transition in Mg-Doped CuGeO_3
V. Kiryukhin, Y. J. Wang, S. C. LaMarra +4
We report a synchrotron x-ray scattering study of the diluted spin-Peierls (SP) material Cu_{1-x}Mg_xGeO_3. In a recent paper we have shown that the SP dimerization attains long-ra…
The first-order phase transition between dimerized-antiferromagnetic and uniform-antiferromagnetic phases in Cu_(1-x)M_xGeO_3
T. Masuda, I. Tsukada, K. Uchinokura +3
We have performed detailed magnetic susceptibility measurements as well as synchrotron x-ray diffraction studies to determine the temperature vs concentration ( - ) phase dia…
Far-Infrared Spectroscopy in Spin-Peierls Compound CuGeO_3 under High Magnetic Fields
K. Takehana, T. Takamasu, M. Hase +2
Polarized far-infrared (FIR) spectroscopic measurements and FIR magneto-optical studies were performed on the inorganic spin-Peierls compound CuGeO_3. An absorption line, which was…
Thermal Conductivity of Mg-doped CuGeO_3
J. Takeya, I. Tsukada, Yoichi Ando +2
The thermal conductivity is measured in a series of Cu_1-xMg_xGeO_3 single crystals in magnetic fields up to 16 T. It has turned out that heat transport by spin excitations is…
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…
Structural Critical Scattering Study of Mg-Doped CuGeO3
Y. J. Wang, V. Kiryukhin, R. J. Birgeneau +3
We report a synchrotron x-ray scattering study of the diluted spin-Peierls (SP) material Cu_(1-x)Mg_xGeO_3. We find that for x>0 the temperature T_m at which the spin gap is establ…
