This patent describes a method for manufacturing a gradiometer having a three-dimensional structure for a device for the single-or multichannel measurement of magnetic fields with field intensities down to less than 10/sup -10/T and in particular, below 10/sup -12/T. At least one superconducting gradiometer coil of predetermined dimensions is arranged a support body and connected by means of superconducting connecting lines and a coupling coil to a superconducting quantum interference element (SQUID) in a magnetically coupling manner. The gradiometer coil and at least the connecting lines associated with the coil are applied as thick or thin films together and simultaneously to a common three-dimensional support body in which at least one coating operation is preceded for the position-wise fixation of the corresponding conductor runs by a lithographic process.
