Monte Carlo simulation of the non-equilibrium critical dynamics of low-dimensional magnetics and multilayer structures

Resumo

The Monte Carlo simulation of the critical behavior of low-dimensional magnets and multilayer structures based on anisotropic Heisenberg mode are presented. The aging and clustering effects are revealed in the critical relaxation of 2d XY-model from non-equilibrium initial states. The investigation of non-equilibrium critical behavior of multilayer structure which correspond to the nanoscale superlattice Co/Cr demonstrates that the aging can be observed in a wider temperature range than for bulk magnetic systems.
