Maria A. Medvedeva. Non-equilibrium critical behavior of thin Ising films [Текст] / Maria A. Medvedeva, Pavel V. Prudnikov, Alexey S. Elin // Journal of Magnetism and Magnetic Materials. — 2017. — Т. 440. — С. 33-36Аннотация:
In this paper we study the non-equilibrium properties of Ising ferromagnetic films using Monte Carlo simulations by short-time dynamic method. We have found thickness dependency of critical exponents z, theta and b/n. Ageing effects were observed in non-equilibrium critical behavior. Former was carried out both from high-temperature and low-temperature initial states. A characteristic time of relaxation, which diverges at a transition temperature in the thermodynamic limit, is obtained as a function of the system size and waiting time.
