Abstract

We determine the onset temperature of the pseudogap corresponding to the precursor of the superconductivity by measuring the out-of-plane resistivity ρc of Bi1.74Pb0.38Sr1.88CuO 6+δ in magnetic fields up to 40 T. It has been found that the semiconducting upturn of ρc(T) below T* is suppressed by the application of magnetic fields up to 40 T at low temperatures below T** which is lower than T*. That is, with decreasing temperature, the magnetic-field insensitive pseudogap is formed below T*, and then the magnetic-field sensitive one participates below T**. These results have confirmed that the pseudogap corresponding to the precursor of the superconductivity is formed below T**.
