Field dependent resistivity measurements have been performed for NdCo2 and PrCo2 compounds.
The influence of the localized 4f-moments, interacting with the 3d-matrix, is accentuated by subtracting the
resistivity of YCo2 from the observed resistivity values. The excess resistivity ???? (= ??(RCo2) - ??(YCo2
)) which is enhanced above TC by the presence of 4f-atoms is strongly temperature dependent. The results
are discussed in terms of the thermal variation of the number of the Co-enhanced paramagnetic atoms. ??
