✦ Synopsis

For a number of (RE, Y)Co, compounds (RE = Er, Dy, Tb, Gd) the influence of the localized 4f moments, interacting with the itinerant 3d matrix, is accentuated by subtracting the resistivity of YCo, from the observed resistivity values. The results show that spin fluctuation scattering is enhanced not only just above Tc in the compounds where the induction of the itinerant Co moments starts, but in the whole paramagnetic temperature range in all investigated compounds.
