Development of High-Field ESR System Using SQUID Magnetometer and its Application to Measurement under High Pressure
We have developed a high-field and high-frequency ESR system using a commercially available magnetometer equipped with the superconducting quantum interference device (SQUID). This is magnetization detection type ESR and ESR is observed as a change of the magnetization at the resonance condition under irradiation of the electromagnetic wave. The frequency range is from 70 to 315 GHz and the max...
متن کاملFour layer monolithic integrated high T, dc SQUID magnetometer
Y13aZCus0,-, based monolithic integrated dc SQUID magnetometers, consisting of a dc SQUID integrated with a flux transformer on a single bicrystalline substrate, have been fabricated and characterized. The devices consist of four layers, including two superconducting layers, and first realizations operate up to 73 K. A maximum voltage modulation of 32 ,u,V is observed at 40 K. A field sensitivi...
متن کاملNoninvasive Measurement of Gastric Propagation Using a Squid Magnetometer
A vector Superconducting QUuntum Interference Device (SQUID} magnetometer wus used to meusure the magnetic fields nssociated with propagation of gustric electrical uctivity. Measurements of the magnetic field vector were consistent with the presumed pattern of current propagation in the gastric musculature. Further studies using two SQUID systems ullowed the first noninvasive determination of t...
متن کاملNoninvasive diagnosis of mesenteric ischemia using a SQUID magnetometer.
OBJECTIVE The authors assessed the ability of a Superconducting Quantum Interference Device (SQUID) magnetometer to noninvasively detect mesenteric ischemia in a rabbit model. SUMMARY BACKGROUND DATA Superconducting Quantum Interference Device magnetometers have been used to detect magnetic fields created by the basic electrical rhythm (BER) and to detect changes in BER of exteriorized bowel ...
متن کاملUltimate limitation of the SQUID magnetometer
The Superconducting QUantum Interference Device is used to detect weak biomagnetic signals since in the early seventies. In that time the measurement was based on point contact rf SQUIDs operated at 20 MHz, with to a flux noise of the order of 10-4 Φ 0/ √Hz . After finding methods to fabricate reliable thin-film devices, the dc SQUIDs started gradually replace the rf SQUIDs. [1] The dc SQUID wi...
