Local Pairs

In this paper we have succeeded in describing the thermoelectric power and the Hall coefficient in the normal state of several underdoped and nearly optimally doped high-T c superconductors within the framework of the two-subsystem (or two-component) model. We analyze the effect of pseudogap on Hall effect and get the temperature T* at which the pseudogap opens. The results agree with those of experiments. The correlation energy of the nearly local pair is in the same order of the magnitude with thermal energy (k B T), so the pairs have somewhat decomposability, therefore, we suggest that the nearly local pairs coexist with itinerant single carriers in the normal state of high-T c superconductors.

Abstract We discuss the application of the positron annihilation angular correlation (ACAR) spectroscopy for investigating the electronic structure and Fermiology of high-Tc superconductors, with focus on the YBa2Cu3O7 system where most of the experimental and theoretical work has to date been concentrated. Detailed comparisons between the measured 2D-ACAR positron spectra and the corresponding band theory predictions show a remarkable agreement (for the normal state), indicat-ing that the electronic structure and Fermi surface of this material is described reasonably by the conventional picture.
