Features of the non-equilibrium critical dynamics in 3D pure and diluted Ising-like ferromagnets

The non-equilibrium critical behaviour of the three-dimensional pure and site-diluted spin systems described by Ising model is studied with different spin concentrations for evolution from various initial magnetic states. The universal scaling functions are determined for the magnetization and autocorrelation function. The aging and superaging effects are revealed in autocorrelation function behaviour for diluted systems with evolution from low-temperature initial states.
