چکیده
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 sensitivity of 0.17 pT/&% is obtained above 200 Hz at 45 K and 0.49 pT/@ at 1 Hz and 65 K.

متن کاملJosephson junctions and DC SQUIDS based on Nb/Al technology.
A process for fabricating high-quality Josephson junctions and DC SQUIDs on basis of Nb/Al technology has been developed. DC magnetron sputtering is used for the deposition of the metal layers and the barrier is formed by thermal oxidation of the Al-layer. The junction area of 5 microns x 5 microns is obtained using anodisation. Three types of Josephson tunnel junctions have been prepared: stan...
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...
متن کاملDouble Relaxation Oscillation SQUID Systems for Biomagnetic Multichannel Measurements
Multichannel superconducting quantum interference device (SQUID) systems based on double relaxation oscillation SQUIDs (DROS) were developed for measuring magnetocardiography (MCG) and magnetoencephalography (MEG) signals. Since DROS provides large fluxto-voltage transfer coefficients, about 10 times larger than the DC SQUIDs, direct readout of the SQUID output was possible using compact roomte...
