  • Abstract
    We have fabricated HTS Josephson Junctions and DC SQUIDs using MgO bicrystals and YBCO thin films grown by PLD. The electrical and noise properties of the junctions have been measured. The SQUIDs have been designed and fabricated for use in our NDE programme. For this reason, their performance in unshielded environments is discussed here.
