Abstract:
We have repeated the simulations of Henkel, Paessens, and Pleimling (HPP) [Phys. Rev. E 69, 056109 (2004)] for the field-cooled susceptibility chi(FC)(t) - chi0 approximately t(-A) in the quench of ferromagnetic systems to and below T(C). We show that, contrary to the statement made by HPP, the exponent A coincides with the exponent a of the linear response function R(t,s) approximately s(-(1+a))f(R)(t/s). We point out what are the assumptions in the argument of HPP that lead them to the conclusion A < a.
