Abstract
We report the result of our accurate measurements of the - and -axis resistivity, Hall coefficient, and the -axis thermopower in untwinned single crystals in a wide range of doping. It is found that both the -axis resistivity and the Hall conductivity show anomalous dependences on the oxygen content in the 60-K phase below the pseudogap temperature . The complete data set enables us to narrow down the possible pictures of the 60-K phase, with which we discuss a peculiar role of the pseudogap in the charge transport.
