Abstract
Behaviour or the Co magnetic moments in dilute PtFe alloys was studied in the temperature range of 5 - 50 mK and the external magnetic field range of 0 - 8.5 T using low-temperature nuclear orientation. Kondo b ehaviour of Co, known to exist in pure Pt, was found in the sample of lowest concentration only (Pt + 0.22 at.% Fe). Large misalignment of t he Co magnetic moments was seen, especially for alloys having Fe conce ntration slightly above the percolation limit 0.76 at.%. An anomaly in the hyperfine field value on the Co nucleus was also found in these a lloys
