The results of a numerical Monte Carlo study of the behavior of a trilayer nanostructure with magnetization oriented in the film plane with ferromagnetic film thicknesses N = 3 and 21 MLs are pre- sented. The non-equilibrium behavior of the structure has been investigated at the critical temperatures Tc(N ) and temperatures Tc(N )/2, Tc(N )/4, and the time dependence of the autocorrelation function dur- ing the evolution from different initial states and the dynamic susceptibility from the high-temperature initial state have been analyzed. Aging effects are revealed in the behavior of the two-temporal char- acteristics. The asymptotic values of the fluctuation-dissipative ratio for the structures with N = 3 and 21 MLs are calculated which indicate the violation of the fluctuation-dissipative theorem in the non-equilibrium behavior of these structures
