Effect of Na content and hydration on the excitation spectrum of the cobaltite Na_xCoO_2 yH_2O

P. Lemmens, V. Gnezdilov, N. N. Kovaleva +8

We report on a Raman scattering study on the superconducting cobaltite $N a_{x} C o O_{2} \cdot y H_{2} O$ as function of Na content and hydration (x $\approx$ 1/3, 3/4 and y $\approx$ 0, 2/3, 4/3)…

Specific heat of unconventional superconductivity in NaxCoO2-yH2O

H. D. Yang, J. -Y. Lin, C. P. Sun +5

Comprehensive studies of the low-temperature specific heat C(T,H) in NaxCoO2-yH2O are presented. At H=0, a very sharp anomaly was observed at T=4.7 K indicating the existence of bu…
