Abstract
The supercurrent-phase relation (CPR) of Nb-Al based Josephson elements of superconductor/insulator/normal conductor/insulator/superconductor-type is deduced from impedance measurements of the phase-biased junction. The chose n temperature range from 1.9 to 8.0 K covers the superconducting transition of the aluminum interlayer below which a pronounced non-harmonic CPR is fo und. At temperatures higher than the corresponding critical temperature, th e CPR did not deviate significantly from purely harmonic shape. Both result s are in agreement with theoretical predictions.
