Behavior of double junction squid of Y-Ba-Cu-O bulk superconductor

· Mod. Phys. Letters B; (United States)
A dc SQUID like geometry with a ring and a pair of constrictions is carved out of bulk Y-Ba-Cu-O superconductor. The I-V curves exhibit hysteresis arising due to trapping of the self fields. The V-Phi curves show multiple flux periodicities with unequal amplitudes. There is twenty fold rise in the amplitude of voltage modulation in cooling from 77 to 4.2 K. The complications of presence of series and parallel arrays of granular junctions are attributed respectively to large and small periodicities observed in V-Phi curves. The modulation structure gets more resolved at 4.2 K due to reduction in thermal noise effects.
