Non-equilibrium critical relaxation of the 3D Heisenberg magnets with
long-range correlated disorder
   [PDF]

Pavel V. Prudnikov, Maria A. Medvedeva
Monte Carlo simulations of the short-time dynamic behavior are reported for three-dimensional Heisenberg model with long-range correlated disorder at criticality, in the case corresponding to linear defects. The static and dynamic critical exponents are determined for systems starting from an ordered initial state. The obtained values of the exponents are in a good agreement with results of the field-theoretic description of the critical behavior of this model in the two-loop approximation.
