A N-S point contact (platinum tip-a&plane of a BiZSr2CaCu208 single crystal) has been used for the first time to detect the vortex motion in a high-T, superconductor. The sweep of an external magnetic field led to the appearance of voltage pulses on the contact (when a constant current was passed t
Very detailed flux creep and relaxation measurements ofintragrain magnetization in sintered high-To superconductors at 4.2 K are presented. The M-relaxation rate is not a single valued function of the applied B-field but depends strongly on the prior magnetic field cycling procedure. The largest rel
It is shown, within a simple model calculation, that the critical current density of an S/N/S junction in a high paralel magnetic field decays exponentially. The comparison of the theoretical results with experimental data for the Pb/Cd/Pb junction and YBCO films is given.
