The noise and transfer parameters of superconducting quantum magnetometers (SQMs) with external feedback (used in multichannel systems to exclude the crosstalk in the antenna system) are analysed. An input equivalent noise circuit is designed and the relations for its parameters in terms of dependen
We calculate the signal-to-noise ratio in a dc SQUID systenz as a function of source impedance, taking into account the effects of current and voltage noise sources in the SQUID. The optimization of both tuned and untuned voltmeters and magnetometers is discussed and typical sensitivities are predic
## 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
