  • "Method of making high Tc superconducting thin films with fullerenes by evaporation"
    Patent number: 5356872
    Abstract: An evaporation method of producing a new high Tc superconducting material using fullerene molecules as artificial pinning sites for any magnetic flux that may enter the material.
    Type: Grant
    Filed: March 17, 1994
    Date of Patent: October 18, 1994
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Walter Eidelloth, deceased, James T. Busch, legal representative, Richard J. Gambino, Rodney Ruoff, Claudia D. Tesche
  • Three junction squid mixer
    Patent number: 5334884
    Abstract: A three junction SQUID (superconducting quantum interference device) mixer circuit is disclosed wherein a nonlinear element such as a Josephson junction is coupled with a dc SQUID formed by two other nonlinear elements such as Josephson junctions and two input coils to provide a mixer circuit that can be employed for mixing two input magnetic flux signals. The mixer can be used for up-converting very low frequency signals, for minimizing and solving problems associated with quantum noise limitations, or for down-converting high frequency signals.
