Macroscopic quantum phenomena in point contacts with high-T sub(c) superconducting material

Relationships between current, voltage, and magnetic field of tin-YBa sub(2)Cu sub(3)O sub(9-y) and YBa sub(2)Cu sub(3)O sub(9-y)-YBa sub(2)Cu sub(3)O sub(9-y) point contacts have been determined. In both cases macroscopic quantum phenomena have been observed, in the form of periodic dependences of...

Zusammenfassung:Relationships between current, voltage, and magnetic field of tin-YBa sub(2)Cu sub(3)O sub(9-y) and YBa sub(2)Cu sub(3)O sub(9-y)-YBa sub(2)Cu sub(3)O sub(9-y) point contacts have been determined. In both cases macroscopic quantum phenomena have been observed, in the form of periodic dependences of the voltage (at constant applied current) on the magnetic field, which are typical for double point contacts (d.c. SQUID's). With YBa sub(2)Cu sub(3)O sub(9-y)-YBa sub(2)Cu sub(3)O sub(9-y) contacts oscillations have been observed up to 66 K.
