Summary

A SQUID magnetometer system designed for low field static and dynamic susceptibility measurements is described. A highly stable direct current magnetic field is generated by a small superconducting solenoid working in the persistent mode. The temperature control system yields a resolution better then 10 microK in the range of 30-100 K. Combining alternating-current susceptibility and direct-current magnetic relaxation measurements, the system allows dynamic susceptibility studies in a time window ranging from 3 microseconds to 1 million seconds. The sensitivity of the system is 1 pico-ampère.m2.
