We have fabricated thin-film dc SQUIDS (Superconducting Quantum Interference Devices) incorporating Nb/Al-Oxide/Nb tunnel junctions. The spectral density of the voltage noise, Sv, of stripline SQUIDS is characterized between 1 Hz and 2000 Hz. responsivi ?% aV/acP) over a significant ran In this fre
