    • Measurements of χ (T) in our Cd0.95 Mn0.05 Se:In sample at 0.1–4.2 K gave the same temperature dependence as found in Ref. 22, but about 30% larger absolute values. We note that magnetic polarons [, ] and disorder (Refs. 14 and 18) may enhance chi.

    • We neglect here the contributions due to the Kondo effect in the WLR (Ref. 10). For material parameters of Cd0.95 Mn0.05 Se (Refs. 20, 21, 23, and 24) the Kondo correction gives [ σ (0.05 K)- σ (4.2 K ) ] / σ0 apeq + 10-6 (the plus sign is given by the sign of α ).

    • C was treated here as an adjustable parameter since its calculation would require several speculative assumptions concerning spin density of s electrons, s vec ( r vec ). With s vec ( r vec ) = size 6 sumi ^ s veci ^ exp ( - | r vec - R veci | / ξ ), assuming Ni = 8.4 times 1017 cm-3_, randomly distributed Ri ""'s, and ξ = aB, one obtains in first Born approximation C = 1.5 times 1015 s-1.
