The surface contact resistivities of high T c superconductors with different methods of connection have been compared. The current -voltage (I-V) characteristics of the contacts have been investigated and analysed. It was found that an amount of silver added to an YBCO superconductor affected the co
It is shown that the quality of contact made to the specimen can lead to wildly erroneous values of Jc' Pulsed current techniques give more reliable Jc values, but the results can still be distorted by the presence of thermoelectric effects. Methods of making contact to these materials are evaluated
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
