Description
Using Monte Carlo simulations we investigate aging behavior during phase ordering in two-dimensional Ising models with disorder and in three-dimensional Ising spin glasses. The time-dependent dynamical correlation length L(t) is determined numerically and the scaling behavior of various two-time quantities as a function of L(t)/L(s) is discussed. For disordered Ising models deviations of L(t) from the algebraic growth law show up. The generalized scaling forms as a function of L(t)/L(s) reveal a simple aging scenario for Ising spin glasses as well as for disordered Ising ferromagnets.
