We study the short time dynamics of a two-dimensional Ising model with a line of defects. The dynamical critical exponent θ associated to the early time regime at the critical temperature was obtained by Monte Carlo simulations. The exponent θ was estimated by a method where the quantity of interest is the time correlation of the magnetization.

The Monte Carlo study of initial states influence on non-equilibrium slow dynamics and two-time dependence of magnetoresistance in multilayer magnetic structures Co/Cu(100)/Co и Pt/Co/Cu(100)/Co/Pt with different types of anisotropy is presented. It was revealed nontrivial aging effects in the magnetoresistance and essential influence of initial states on the magnetoresistance.

Dynamical Exponents

We present a dynamic Monte Carlo study of the spin-1/2 quantum XY model in two-dimensions at the Kosterlitz–Thouless phase transition temperature. The short-time dynamic scaling behaviour is found and the dynamical exponents θ, z and the static exponent η are determined.
