Included:  M(H) at 1.4 and 4.2 K on powder samples of antlerite, to ~58 T in a pulsed magnet

Magnetization is in arbitrary units

I believe the conversion to a fraction of saturation magnetization was done by our theory collaborators

We have data at 4.2 K, which overlaps with single-crystal magnetization data collected for the second paper
This could conceivably be used to calibrate this very approximately.  
But only two field orientations were measured at that point, on crystals and not powder, and no M(H).
There is literature M(H) available, e.g. in the Hara paper, J. Phys. Soc. Jpn. 80, 043701 (2011), https://doi.org/10.1143/JPSJ.80.043701
