OPM Gradiometer for Magnetorelaxometry
, 2022 Magnetic nanoparticle (MNP) applications in biomedicine require the MNPs characterization, quantification, and spatial distribution determination. These are tasks that can be performed by magnetorelaxometry (MRX). Until recently, SQUIDs were the most commonly used sensors to detect MRX signals.

IEEE Transactions on Applied Superconductivity, 2006 We present methods to compute the imbalance in a gradiometer of arbitrary shape due to imperfections in its geometry, eddy currents induced in the radio-frequency interference shield, and screening currents induced in the modules of the superconducting quantum interference devices (SQUIDs). As an example, the methods are applied to evaluate the maximum
