Notes:
An electronic circuit has been developed to study the pulse I–V characteristics of superconductors. A special feature of the circuit is its low rms noise voltage of less than 10 nV, which allows measurements over a broad voltage range of 50 nV to 500 mV for the first time. In order to overcome the limitations of a four probe technique at high common mode voltages, a novel five probe geometry is developed. The measurements on single crystals of the Bi2Sr2CaCu2Ox superconductor are carried out to demonstrate the circuit performance.
