✦ Synopsis

In this contribution we briefly describe our newest 24-channel neurogradiometer, employing dc SQUIDS as magnetic flux sensors, and present an example of its performance. The instrument is used in a magnetically shielded room. This state-of-the-art apparatus is able to locate the stimulus-activated area in the brain by just one measurement, without moving the dewar.

SQUID gradiometers are attractive for magnetic field measurements in noisy environments. A first-order planar gradiometer has been designed and fabricated. The layout of the planar gradiometer used to have two symmetric pickup coils; however, our design adopted one compensation loop with the same si

We describe the use of liquid helium-cooled (4.2 K) gradiometer coils and a DC superconducting quantum interference device (SQUID) preamplifier to improve the SNR of magnetic resonance imaging (MRI) at 0.01 T. Gradiometer windings are used both to reduce lossy interactions with the MRI system's room

## Abstract We have developed concentric multiloop DC‐SQUID gradiometers for nondestructive evaluation, which were integrated on a 3 × 3 mm^2^ Si chip using Nb thin‐film fabrication technology. In order to obtain high spatial resolution and to cancel magnetic noise, a coplanar concentric second‐ord
