TI2Ba2CaCu2Ox Bicrystal Junction DC-SQUID Magnetometers Operating in Unshielded Environment
-
Abstract
We fabricated direct-current superconducting quantum interference device magnetometers with single layer epi-taxial Tl2Ba2CaCu2Ox films on 36.8o SrTiO3 bicrystal substrates. The white Aux noise and the field-flux transformation coefficient of the devices are 1.5 x 10-5Φ0/√Hz and 40 nT/Φ0, respectively. The magnetometers can work in unshielded environment.
