    • For strong, weakly temperature dependent paramagnets like elements and alloys of the (formula presented) (formula presented), and (formula presented) transition series (Pd below 300 K, for instance) typical values are about (formula presented). For example, (formula presented) is found for pure Pd and (formula presented) for alloys as (formula presented) or (formula presented). A completely temperature independent Pauli contribution would be associated with much lower values. On the other hand, a strong Curie contribution is not aparent in the low temperature, vs, curves, which do not show any upturn. From the high field slope of a hysteresis cycle measured at 5 K, we estimated un upper limit, (formula presented). Such a Curie term would be less relevant at 200 K, a simple estimation rendering (formula presented). Attempts of including a paramagnetic term of reasonable magnitude (formula presented) in the fits were unsuccesful
