要旨

We present a study of heat and charge transport in Bi2+xSr2-xCuO6+delta
focused on the size of the low-temperature linear term of the thermal
conductivity at optimal-doping level. In the superconducting state, the
magnitude of this term implies a d-wave gap with an amplitude close to
what has been reported. In the normal state, recovered by the
application of a magnetic field, measurement of this term and residual
resistivity yields a Lorenz number L=kappa(Nrho0)/T=1.3+/-0.2L(0). The
departure from the value expected by the Wiedemann-Franz law is thus
slightly larger than our estimated experimental resolution.
