ABSTRACT:
For manufacturing a gradiometer having a three-dimensional structure for a single or multi-channel device for measuring magnetic fields with field intensities to below 10.sup.-10 T, the superconducting gradiometer coils of predetermined dimensions lying in different planes are connected to each other via superconducting connecting lines and are coupled to at least one superconducting quantum interference element (SQUID). The connecting lines are designed in a simple manner. First, the gradiometer coils are applied in spaced position, with the connecting lines running between the coils, to an at least largely planar flexible substrate body. Then, the substrate body is bent such that the three-dimensional gradiometer structure is obtained. For the substrate body, a thin polyimide foil, in particular, can be used.
