Josephson tunneling I-V characteristics have been observed in break j unctions of oxygen-annealed Bi2Sr2CaCu2Os (Bi-2212 ) single crystals, with foR. ~ 21.3 mV, and with a sharp quasipartiele edge at 2zt ~ 2 × 20 mV. This demonstrates that low values of the IoR. product, thus far as observed in HTS

We report on N-I-S point contact and S-I-S break junction tunneling measurements at T=4.2 K on Bi2Sr2CaCu2Os+6 single crystals (Tc = 78-86 K). For the latter experiments, the breaking of the crystal was done in liquid He atmosphere in order to produce clean surfaces. The superconducting energy gap s
The behavior of the in-plane penetration depth l(T) extracted from the reversible magnetization in different magnetic fields for Bi 2 Sr 2 CaCu 2 O 8+d single crystal is investigated. It is found that the temperature dependence of penetration depth in different fields follows a quadratic function be
