The first three columns give the Moskowitz test parameters, and the rest of the columns give the room temperature FMR parameters (see refs. 14 and 16). For each spectrum, we report the effective g factor (geff), the peak-to-peak linewidth in the derivative spectrum (ΔB), and asymmetry ratio A ≡ ΔBhigh/ΔBlow. See figure 2a of ref. 14 for a graphical depiction of these FMR parameters. The carbonate sample was too weak to be detected with the Magnetic Property Measurement System for the Moskowitz test, whereas the chromite sample was too weak to be detected with FMR at both room temperature and 77 K.
