Abstract
AC susceptibility and electrical resistivity measurements have been carried out on a series of dilute PdMn alloys containing between 0.5 and 2.5 at.% Mn. The AC susceptibility taken in various collinear biasing fields exhibits a maximum in the vicinity of the Curie temperature as predicted by the scaling law equation of state. Further, the field dependence of these maxima is uniquely governed by the critical index delta , and estimates for this latter index have been made along the index gamma and the Curie temperature Tc. The electrical resistivity data, taken on the same samples, are in good overall agreement with the results obtained from the susceptibility study.
