摘要：

The small signal rf impedance of Y1Ba2Cu3O7-delta step edge junction rf SQUIDs operating in a strongly nonhysteretic mode has been measured. The phase dependent inductance L(J)(phi) and the current phase relation I-p(phi) of step-edge junctions embedded in SQUIDs are calculated from measurement data following the Vincent-Deaver approach. Two of three junctions investigated revealed a sinusoidal current phase relation. I-p(phi) of the third junction seemed to be non-sinusoidal and hysteretic. A model explaining the origin of the non-sinusoidality of I-p(phi) is proposed.
