  • Abstract
    The design, construction, and performance of miniature SQUID (superconducting quantum interference device) susceptometers is discussed. Spins (in units of μβ) per √Hz has been identified as an important figure of merit. Simple expressions for Sn (spin sensitivity) in miniature SQUID susceptometers are developed and the implications of dimensional scaling explored. The details of several existing and proposed designs are reviewed, including versions that utilize commercial SQUIDs. With thin-film DC SQUIDs, Sn values of a few thousand spins/√Hz have already been obtained, and it is projected that values of a few hundred will be achieved soon
