  5. 4. Key Components for High Tc SQUID Magnetometers

    Författare :Per-Åke Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes the development of key components for superconducting quantum interference device (SQUID) magnetometers in the high temperature superconductor YBa2Cu3O7 (YBCO). Such magnetometers are made for liquid nitrogen temperature operation, as opposed to low Tc devices that are confined to liquid helium. LÄS MER
