Abstract :
Thin-film weak link rings were constructed using high-T c YBaCuO superconducting thin films. The thickness of the films was 5000 Å. The weak links were biased with an AC induced current. The resulting electron pair charges on the weak links were monitored by an output voltage. The charge stored on the link (as a function of the input bias voltage) is consistent with that of a macroscopic quantum pendulum
