摘要：

Two recently published comments [P. A. Beck, Phys. Rev. B 39, 752 (1989) and D. Boumazouza et al., Phys. Rev. B 39, 749 (1989)] have drawn attention to the interesting magnetic behavior of reentrant spin-glass systems. We present a temperature-dependent Mossbauer-effect study on Cr74Fe26 alloy whose composition is close to and slightly above the percolation threshold (x(Fe) = 19.9 at. %), to resolve the controversy that has arisen out of these discussions. Our results suggest that the nature of magnetic ordering at the paramagnetic-to-ferromagnetic transition in this system also does not correspond to a true cooperative transition, as pointed out by Beck for Au82.5Fe17.5 alloy.
