Superconducting quantum interference devices (SQUIDs) are intrinsically very sensitive detectors of magnetic flux. Flux sensitivities of one millionth of a flux quantum per root Hz (1μφ0/√Hz) may typically be realized in low-temperature supercond

A SQUID (Superconducting Quantum Intereference Device) rotating tensor gradiometer has been test flown in a helicopter-towed bird over a magnetic dipolar source. The bird was instrumented with fluxgates, tiltmeters, a gyroscope and GPS receivers to a

We have designed and fabricated a new range of thin-film superconducting true-field magnetometers (TFM) for use in detecting the true value of the magnetic field. Our TFMs enhance the applied magnetic field sensed at a Josephson junction by up to 70

The design of a new-concept axial gradiometer is discussed, which employs a gradiometric pick-up loop formed by etching a transformer loop structure on flexible superconducting tape. The pick-up loop is inductively coupled to a SQUID magnetometer. Se
