Description
Following a suggestion by I.A. Campbell, we have conducted Moessbauer source experiments on disordered alloys of 57CoPd80Co2o in search for evidence of random anisotropy (RA) effects on critical behavior. The result, β=0.38(3) in the reduced temperature range 10-2<1-T/Tc<0.2, though not strictly asymptotic, is consistent with the d=3 Heisenberg model, with no evidence for RA. In this paper we argue that among transition metal ferromagnetic alloys there are no better candidates for RA effects than our chosen system. (orig.)
