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