| Zusammenfassung | The amplitude of the cos φ-term of the current phase relationship for a superconducting point contact in a RF-SQUID can be evaluated from the DC-flux-dependence of the Q of the tank circuit. An explicite expression for α is given on the basis of the general theory for nonhysteretic SQUIDs. Measurements performed on Nb-point-contacts at 4.2 K lead to α = -0,65 ± 0.06. |
