摘　　要：We fabricated direct-current superconducting quantum interference device magnetometers with single layer epi-taxial Tl_(2)Ba_(2)CaCu_(2)O_(x) films on 36.8° SrTiO_(3) bicrystal substrates.The white Aux noise and the field-flux transformation coefficient of the devices are 1.5 × 10^(-5)Φ0/√Hz and 40 nT/Φ0,respectively.The magnetometers can work in unshielded environment.
