Evaluation of a long-time temperature drift in a commercial Quantum Design MPMS SQUID magnetometer using Gd$_2$O$_3$ as a standard

摘要

The long-time temperature drift in a commercial Quantum Design MPMS SQUIDmagnetometer was evaluated using time-dependent magnetization measurements ofGd$_2$O$_3$. In contrast to earlier claims, the amplitude of the drift wasfound not to exceed 1-1.5 K. 30 minutes after system stabilization thetemperature deviation did not exceed 0.2 K and the temperature was fullystabilized in less than 3 hours.
