Fig. 3. Example DC decay measurement. Samples are saturated at high magnetic field before the field is swept to the target field. In a Quantum Design MPMS3 the fastest field sweep rate is 700 Oe s−1, such that it takes ≈100 s to go from 7 T to 0 T. The x-axis is set to t = 0 s at M0, and Meq is not shown on this scale.
