Abstract:	A dc ¿ SQUID consists of a superconducting ring interrupted by two Josephson junctions, one of which carries in equilibrium a ¿ phase difference, caused, for example, by the d-wave pairing symmetry of the high- Tc cuprates. If this phase shift is maintained in the voltage state, anomalous resonance currents are expected in the SQUIDs transport characteristics. Here we report the observation of such resonances for high- Tc dc ¿ SQUIDs, providing evidence for the influence of the d-wave symmetry on the voltage state of a Josephson junction for frequencies of several tens of GHz.
