Measurements down to ~1.8 K in a Cryogenic Ltd. CFMS using the VSM option:  CFMS subdirectory

In all cases:
mass = 0.0596 g
lock-in time constant = 0.3 s
VSM frequency = 21.50 Hz
B_analog_(T) is the measured field
sensor_B_(K) is the sample temperature
moment_(emu) is the magnetic moment in emu

M(T) files typically start with ZFC warming, then cool back to base T in the same field (FCC), then rapidly return to a higher temperature in preparation for the next ZFC run
There are several types of glitch in the data, most notably spikes that take 3 data points (3 time constants on the lock-in) to vanish, or cases (especially in field sweeps) where the program stopped writing data briefly then wrote 2-3 nonsense points at one field before continuing.  
On warming, there is usually a large glitch around 14 K where the cooling mode changes, especially for fast ramp rates.  This glitch is not physically meaningful.
The magnet power supply has a discontinuity at ±1.00 T, leading to a small step in the data.  This was not removed in our plots.
True zero field at the sample position is achieved for an applied (and measured) field of around +0.008 T.

Data collected in a Quantum Design MPMS with the iHelium3 option at the IFW-Dresden:  iHelium3_IFW subdirectory:

Raw data files are not available.  The files contain molar M/H as a function of T (K).

Columns are H (T), M (arbitrary units), dM/dH

Columns are H (T), M (arbitrary units) for increasing field, H (T), M (arbitrary units) for decreasing field


Limited additional data were collected in a Quantum Design MPMS with a reliable absolute calibration, and without background issues associated with some other measurements' sample holders
These data were used to scale the other data, but were not intended for graphing and do not appear in the paper.
This is the same sample as the ³He data above, but with reduced mass (2.19 mg) because a small piece cracked off.
