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…
Enhanced critical current density of YBa2Cu3Ox films grown on Nd1/3Eu1/3Gd1/3Ba2Cu3Ox with nano-undulated surface morphology
R. L. Meng, T. H. Johansen, I. A. Rusakova +5
We report a simple and easily controllable method where a nano-undulated surface morphology of Nd1/3Eu1/3Gd1/3Ba2Cu3Ox (NEG) films leads to a substantial increase in the critical c…
Comparative Raman Studies of Sr2RuO4, Sr3Ru2O7 and Sr4Ru3O10
M. N. Iliev, V. N. Popov, A. P. Litvinchuk +5
The polarized Raman spectra of layered ruthenates of the Srn+1RunO3n+1 (n=1,2,3) Ruddlesden-Popper series were measured between 10 and 300 K. The phonon spectra of Sr3Ru2O7 and Sr4…
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…
