Evaluation of a long-time temperature drift in a commercial Quantum Design MPMS SQUID magnetometer using Gd2O3Gd2O3 as a standard

The long-time temperature drift in a commercial Quantum Design MPMS SQUID magnetometer was evaluated using time-dependent magnetization measurements of Gd2O3Gd2O3. In contrast to earlier claims, the amplitude of the drift was found not to exceed 1–1.5 K. After system stabilization for 30 min, the temperature deviation did not exceed 0.2 K and the temperature was fully stabilized in less than 3 h.
