We report a single-beam synthetic gradiometer operated in the spin-exchange-relaxation free (SERF) regime, using the structure of two separate atomic vapor cells spaced 2 cm apart. To improve the ...

Abstract: We have succeeded in fabricating a high-temperature superconducting (HTS) thin-film gradiometer with small imbalance by applying an HTS multilayer process, including crossovers, ...

The magnetic tensor gradiometer, which is used for measuring the spatial derivatives of three orthogonal magnetic field components, is an important magnetic field characterization tool. Here, the ...
