Several detection platforms can perceive and quantify magnetic labels. Magnetic microchips, superconducting quantum interference devices (SQUID), magnetometers, scanning probes, and induction techniques have this capability. While each magnetic detection technology offers strengths in one area... gain from SQUID technology. Superconducting magnetometers are noninvasive and thus allow the examination of fetal development at an earlier stage than other systems. "PET and MRI systems require radioactive isotopes or generate high energy fields, both of which can damage developing fetuses," says...

...temperatures. Small and inexpensive magnetoresistor sensors can also be used to detect magnetic fields, but the devices aren 't very sensitive. NIST 's prototype merges the useful characteristics of a SQUID and a magnetoresistor sensor. It reaches the SQUID 's high sensitivity levels but is small...

  • Magnetic ordering in hexagonal PrCuSi
    All the remaining physical properties reported in this work were measured on a commercial PPMS station from Quantum Design (San Diego), and magnetic data were collected on an MPMS equipped with a SQUID magnetometer from the same manufacturer . .
  • High magnetic field study of RuSr2GdCu2O8
    A SQUID magnetometer of the same manufacturer was utilized for the ac-susceptibility measurements.
  • Magnetic susceptibility imaging for nondestructive evaluation [using SQUID magnetometer]
    Frustrating the enthusiasm of users and manufacturers of SQUID for NDE applications is the widespread mi5 perception, held by much of the NDE community, that SQUID magnetometers are suitable only for use in low temperature laboratories and cannot be operated in the...
  • Superconducting electronics coming to market
    Other, usually small, manufacturers of LTS SQUIDS have been offering SQUID components, more custom-designed magnetometer systems and also SQUID amplifiers [181 suit- able for research purposes.
  • Sensitive SQUID magnetometry for studying nanomagnetism
    In conclusion, our detailed analysis of artifacts and limitations of commercial MPMS SQUID magnetometers demonstrates that reaching the intrinsic sensitivity of about 5× . 10−9 emu (according to the manufacturer ’s specification) is very challenging if not impossible for samples of...
  • Nondestructive evaluation of wires using high-temperature SQUIDs
    Now, in a somewhat related manner, a shielded high-temperature SQUID magnetometer at liquid-nitrogen temperature has been used to investigate the possibility of detecting interior defects in both normal and superconduc- tive wires as they are being fabricated. This investigation began when a wire manufacturer asked if it would be possi- ble to detect Si...
  • Water absorption in a fired-clay brick observed by NMR scanning
    The authors wish to thank J Noyen, H Otten, H Smulders and AWB Theuws for their indispensable help in building the equipment and performing the NMR experiments, and the group Cooperative Phenomena at EUT for the measuremen& with the SQUID magnetometer . This project was financially supported by the Royal Association of ‘Dutch Brick Manufacturers (KNB). . References .
  • Simultaneous Fetal Magnetocardiography and Ultrasound/Doppler Imaging
    ...magnets used to latch the display cover, which were subsequently removed with the aid of the manufacturer . The periodic interference from the scanner had to be mea- sured with the SQUID magnetometer due to its lower ampli- tude.
  • Performance of a human-size magnetic shield of cylindrical structure with magnetic shaking enhancement
    The white noise level of the SQUID system provided by a manu- facturer is 16 ff/I/Hz in the range 10- 100 Hz. The height of the dewar containing the SQUID magnetometer is 43.5 cm.
  • Magnetic properties of HfO2 thin films
    ...films and the signal recorded with the sample oscillating around the center of the SQUID pickup coils. In this configuration the magnetometer manufacturer gives an absolute sensitivity of 1 × 10−11 A m2 (1 × 10−8 emu) at 0.25 T and an accuracy of 0.1% for a standard sample (cylinder of φ = 3 mm, h = 3 mm).
