Abstract
The static critical exponents alpha, beta, gamma and delta near the Curie t emperature of the reentrant systems Au0.81Fe0.19 and Ni0.78Mn0.22 are deter mined by a variety of methods. The values found for these indices are inter mediate between the predictions for the 3D Heisenberg model and those chara cterizing a spin-glass transition. (C) 2001 Elsevier Science B.V.
