中文摘要	A flip-chip-type gradiometer has been constructed with a 10 mm x 5 mm planar DC-SQUID gradiometer fabricated on a SrTiO3 bicrystal substrate and a flux transformer made from a YBCO* //YBCO/CeO2/YSZ multilayer on a phi 50.8 mm Si wafer. The coupling coefficient between the flux transformer and the planar gradiometer is 0.18. The transformer increases effectively the resolution of the gradiometer. A magnetic field gradient resolution of 73 fT. cm(-1).Hz(-1/2) in the white region and 596 fT.cm(-1)Hz(-1/2) at 1 Hz has been obtained. High quality magnetocardiogram signals have been successfully measured by using this flip-chip-type gradiometer in an unshielded environment.
