Research Abstract

We have developed a SQUID pico-voltmeter for highly sensitive measurement system. Using a low noise high-Tc SQUID sensor and tight coupling circuit for the transfer of the signal voltage, we demonstrated the voltage noise of about 10 pV/Hz^<1/2>. We also developed a magnetic sensor system using the SQUID pico-voltmeter coupled to a pickup coil cooled at 77 K. The sensor showed the field noise of 1 fT/Hz^<1/2> for the frequency f> 20 kHz.
