Magnetic susceptibility in the normal phase of Bi2Sr2CaCu2O8+δ single crystals
Abstract
We report on measurements of the c-axis component of the magnetic susceptibility in the normal phase of several single crystal samples of the Bi2Sr2CaCu2O8+δ cuprate superconductor. These crystal were submitted to appropriate heat treatments so that the density of hole carriers could be varied in an extended region of the superconducting dome. In general, the measured susceptibility shows significant temperature dependence, which was attributed to the pseudogap phenomenon. The results were interpreted with basis on a phenomenological model that allows the determination of the pseudogap characteristic temperature T* as a function of the carrier density.
