Mobility analysis of FeTe thin films
I. Tsukada, M. Hanawa, Seiki Komiya +4
The Hall effect is investigated in detail for nonsuperconducting and superconducting FeTe thin films. The Hall coefficient commonly exhibits a sign reversal from positive in a high…
Doping evolution of the electronic specific heat coefficient in slightly-doped La2-xSrxCuO4 single crystals
Seiki Komiya, I. Tsukada
Detailed doping dependence of the electronic specific heat coefficient gamma is studied for La2-xSrxCuO4 (LSCO) single crystals in the slightly-doped regime. We find that gamma sys…
Physical properties of misfit-layered (Bi,Pb)-Sr-Co-O system: Effect of hole doping into triangular lattice formed by low-spin Co ions
T. Yamamoto, K. Uchinokura, I. Tsukada
Pb-doping effect on physical properties of misfit-layered (Bi,Pb)-Sr-Co-O system, in which Co ions form a two-dimensional triangular lattice, was investigated in detail by electron…
Magnetic excitations in coupled Haldane spin chains near the quantum critical point
A. Zheludev, T. Masuda, I. Tsukada +4
Two quasi-1-dimensional S=1 quantum antiferromagnetic materials, PbNi2V2O8 and SrNi2V2O8, are studied by inelastic neutron scattering on powder samples. While magnetic interactions…
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…
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…
The phase transition between dimerized-antiferromagnetic and uniform-antiferromagnetic phases in impurity-doped spin-Peierls cuprate CuGeO3
T. Masuda, A. Fujioka, Y. Uchiyama +2
We discovered a first-order phase transition between dimerized-antiferromagnetic and uniform-antiferromagnetic phases in impurity-doped spin-Peierls (SP) cuprate Cu{1-x}MgxGeO3. As…
