The surface states of Bi 2Γx Pb x Sr 2 CaCu 2 O 8ΓΎy (Pb-Bi-2212, x ΒΌ 0:6) single crystals are investigated by scanning tunneling microscopy/spectroscopy in order to clarify the origin of inhomogeneous superconducting states. The topography obtained at a cleaved surface of Pb-Bi-2212 showed the coexi
An experimental study of the magnetic irreversibility lines has been carded out on superconducting single crystals of Bi2\_,,Pb~Sr2CaCuO2Os, with and without lead. The irreversibility field values Bird(T) are almost identical for x= 0 and x= 0.4. However, the power-law fits of Bi~(T) ~ 1 / T" at low
