Pressure dependence of the superconducting transition and electron correlations in Na_xCoO_2 \cdot 1.3H_2O
E. Kusano, S. Kawasaki, K. Matano +4
We report T_c and ^{59}Co nuclear quadrupole resonance (NQR) measurements on the cobalt oxide superconductor Na_{x}CoO_{2}\cdot 1.3H_{2}O (T_c=4.8 K) under hydrostatic pressure (P)…
Na content dependence of superconductivity and the spin correlations in Na_{x}CoO_{2}\cdot 1.3H_{2}O
Guo-qing Zheng, Kazuaki Matano, R. L. Meng +2
We report systematic measurements using the ^{59}Co nuclear quadrupole resonance(NQR) technique on the cobalt oxide superconductors Na_{x}CoO_{2}\cdot 1.3H_{2}O over a wide Na cont…
Field-Induced Resistive Switching in Metal-Oxide Interfaces
S. Tsui, A. Baikalov, J. Cmaidalka +6
We investigate the polarity-dependent field-induced resistive switching phenomenon driven by electric pulses in perovskite oxides. Our data show that the switching is a common occu…
Phonons and Magnetic Excitations in Mott-Insulator LaTiO
M. N. Iliev, A. P. Litvinchuk, M. V. Abrashev +4
The polarized Raman spectra of stoichiometric LaTiO (T K) were measured between 6 and 300 K. In contrast to earlier report on half-metallic LaTiO, neither st…
Water Content and Superconductivity in Na0.3CoO2*yH2O
J. Cmaidalka, A. Baikalov, Y. Y. Xue +2
We report here the correlation between the water content and superconductivity in Na0.3CoO2*yH2O under the influences of elevated temperature and cold compression. The x-ray diffra…
Thermodynamic properties in the normal and superconducting states of Na(x)CoO(2)*yH(2)O powder measured by heat capacity experiments
B. Lorenz, J. Cmaidalka, R. L. Meng +1
The heat capacity of superconducting Na(x)CoO(2)*yH(2)O was measured and the data are discussed based on three different models: The thermodynamic Ginzburg-Landau model, the BCS th…
