We have studied the transition rate from the zero-voltage state in a dc SQUID as a function of applied flux and temperature. We observe a crossover from thermal activation to macroscopic quantum tunneling at a flux-dependent temperature. The thermal rates are significantly suppressed, suggesting tha

A new kind of superconducting device, a 4-terminal SQUID, has been fabricated. It consists of a Josephson 4-terminal junction of which two terminals are short-circuited by a superconducting ring and the other two are connected to a current source, forming the transport circuit. Oscillations in the v
