Abstract
The dynamic scaling for the avalanche process in random field Ising model (RFIM) using numerical simulations was studied. This power-law evolution turns into the dynamic behavior described by the Kolgomorov-Johnson-Mehl-Avrami (KJMA) equation. Using the short-time dynamic scaling near the critical point, the critical strength of random field Dcand related critical exponents in the 2D RFIM were determined. Although numerical in nature, an efficient way of obtaining the equilibrium scaling exponents for disordered systems was proposed.
