Best‐fit parameters for field and temperature sweep measurements showing the manganese content (N) and magnetic moment (m) in spores of three species of Bacillus

	Field sweep (T = 5 K)		Temperature sweep (H = 1,000 Oe)
Species	N (×1022 kg−1)	m (µB)	C (×10−6 m3 K kg−1)	m (µB)
B. megaterium	1.55 ± 0.08	5.9 ± 0.2	1.06 ± 0.03	5.7 ± 0.3
B. cereus	2.3 ± 0.1	5.1 ± 0.2	1.68 ± 0.02	5.3 ± 0.2
B. subtilis	4.2 ± 0.3	5.5 ± 0.3	3.22 ± 0.07	5.7 ± 0.2

Field sweep data have been fitted to Equation (3). Temperature sweep data have been fitted to Equation (5) and the corresponding m was calculated using Equation (6).
