摘要：
The Monte Carlo simulation of the critical behavior of multilayer structures based on anisotropic Heisenberg model is performed. The analysis reveals aging effects characterized by a slowing down of the relaxation and correlation characteristics in the system with the waiting time. The dependence of aging characteristics on thickness of ferromagnetic films is investigated. The investigation of nonequilibrium critical behavior of multilayer structure which correspond to the nanoscale superlattice Co/Cu/Co demonstrates that the aging effects can be observed in a wider temperature range than for bulk magnetic systems.
