Abstract
A gradiometer loop system is provided for a device for the multi-channel measurement of very weak magnetic fields where the superconducting gradiometer loops are combined in at least one array and arranged on a carrier body and, like superconducting connecting leads to be connected to them are designed as thin film structures. The gradiometer loops are arranged on the two flat sides of a carrier foil distributed such that together they occupy an at least approximately closed array area, and the connecting leads are designed in the region of the array area placed so that they are shielded at least largely by means of conductor runs to gradiometer loops located on the respective opposite flat side of the carrier foil.
