  • Abstract
    Fine structure of VRFvs IRFdependence of the rf SQUID in the hysteretic mode is investigated experimentally at temperatures from 0.5 to 4.2 K. A suggestion is made that for high resistance point contacts of small capacitance the SQUID sensitivity may be limited by quantum processes for temperatures high enough ( T\\simeq 4 K). To explain the experimental results macroscopic quantum tunneling and zero-point fluctuations are considered as relevant mechanisms.
