Description:

Two types of first-order gradiometers equipped with 50 mm diameter pickup coils were made out of an REBaCuO High-Tc superconducting (HTS) flexible tape. The HTS tapes were formed into the HTS gradiometers by "cut-and-wind" method without cable jointing. Both HTS gradiometers were examined at 77K for magnetic sensitivity for a gradient field applied by external coil. The axial-type HTS gradiometer eliminated a magnetic field output of the device induced by a uniform field, and enhanced a magnetic field output　induced by a gradient field on the axis of the pickup coil. The planar-type HTS gradiometer made it possible to detect a 20 mm diameter steel cylinder placed beside the pickup coil in a uniform field of 100 µT through sensing the spatial field gradient in the vicinity of ferromagnetic object.
