Abstract
The small signal rf impedance of Y1Ba2-Cu3O7-δ step edge junction rf SQUIDs operating in a strongly nonhysteretic mode has been measured. The phase dependent inductance LJ(φ) and the current phase relation Ip(φ) 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. Ip (φ) of the third junction seemed to be nonsinusoidal and hysteretic. A model explaining the origin of the non-sinusoidality of Ip (φ) is proposed.
