Abstract

Two kinds of pseudogap temperatures T* and T** are deduced from the out-of-plane resistivity of Bi_1.74Pb _0.38Sr_1.88CuO_6+δ in magnetic fields up to 27 T. The pseudogap formed at T* is independent of the magnetic field, while another pseudogap at T** is suppressed by the application of magnetic fields. Taking into account that hole-concentration and magnetic-field dependences of T** resemble those of the superconducting transition temperature T_c, the pseudogap temperature correlating to the superconducting gap is not T* but T**.
