We report the result of our accurate measurements of the a- and b-axis resistivity, Hall coefficient, and the a-axis thermopower in untwinned YBa(2)Cu(3)O(y) single crystals in a wide range of doping. It is found that both the a-axis resistivity and the Hall conductivity show anomalous dependences on the oxygen content y in the 60-K phase below the pseudogap temperature T(*). The complete data set enables us to narrow down the possible pictures of the 60-K phase, with which we discuss a… CONTINUE READING
