Show Abstract
Measurements of the magnetoresistance R(H) as functions of the temperature and the angle θ between the applied magnetic field and the plane of a (Bi,Pb)2Sr2Ca2Cu3O/Ag tape have been performed in a low magnetic field region below Tc. Contrary to the two-dimensional vortex pancake model, the data do not scale well with H sin(θ) for small angles. Instead, our results show a general three-dimensional scaling behavior based on the anisotropy in the upper critical field Hc2 over entire angular range. From the scaling, the dissipation anisotropy is found to be unchanged at lower temperatures and decreases with increasing temperature at temperatures close to Tc. © 1998 American Institute of Physics.

Show Abstract
Basic characteristics of a simple single-flux-quantum (SFQ) logic gate using high-Tc material and Josephson junction (NdBa2Cu3O7−δ and focused ion beam junction) have been investigated. The logic gate consists of an rf-superconducting quantum interference device (rf-SQUID) and a dc-SQUID. In the logic gate, elementary SFQ logic operations, such as generating SFQ (dc/SFQ) and providing simultaneous readout (SFQ/dc), have been confirmed up to 50 K. The temperature dependencies of the output voltage level and the critical current-normal resistance (IcRn) product were compared, and the decreasing tendency of the output voltage level for increasing temperature was found to be more rapid than that of the IcRn product. © 1998 American Institute of Physics.
