Temperature dependence of DC SQUID magnetometer performances

Description

We report experimental results on temperature dependence of the main characteristics of fully integrated DC SQUID magnetometers realized on niobium technology. At T=4.2 K the sensor shown a white magnetic field noise spectral density of 2.9 fT/Hz1/2. A slow increase of the field noise (about 20%) was observed with increasing temperature up to 5 K, giving a considerable tolerance of the working temperature of niobium magnetometers in some innovative multichannel systems for magnetoencephalography
