The role of doping and dimensionality in the superconductivity of NaxCoO2
M. Banobre-Lopez, F. Rivadulla, R. Caudillo +3
We report a complete analysis of the formal oxidation state of Co in NaxCoO2, in the interval 0.31<x<0.67. Iodometric titration and thermoelectric power confirm that a direct relat…
Quantum critical behaviour in NaxCoO2
F. Rivadulla, M. Banobre-Lopez, M. A. Lopez-Quintela +1
We report the divergence of the nonlinear component of the bulk susceptibility in NaxCoO2 (0.3<x<0.62) as T goes to 0 K. These experiments provide an striking evidence of the exist…
The origin of the glassy magnetic dynamics of the phase segregated state in perovskites
F. Rivadulla, M. A. Lopez-Quintela, J. Rivas
In this paper we address many of the fundamental open questions regarding the glassy behavior of the magnetic/electronic phase segregated state in rare earth perovskites. In partic…
