摘要：

All high-T(c) dc-SQUID magnetometers made of Bi-Sr-Ca-Cu oxide films were designed and fabricated. A directly-coupled scheme where a SQUID loop and a pick-up loop are connected directly in parallel was chosen to avoid fabricating the multi-layered structure. The flux noise which was measured in FLL operation at 4.2K increased in a form of 1/f as the frequency decreased below 20Hz. The level of white noise at the frequency range above 20Hz was about 1x10(-4)-PHI-0/square-root Hz corresponding to the field resolution of 1.5pT/square-root Hz at the pick-up loop.
