We report theoretical and numerical results on scaling laws for systems with multiple time scales in the context of kinetic dynamics of domain growth [1]. The theoretical method has been tested by Monte Carlo simulations in classical magnetic systems. In particular, we show that in the case of a planar magnetic Heisenberg model with long-range interactions the characteristic length of the domain growth behaves according to a Lisfshitz-Allen-Cahn law with logarithmic corrections [2]. Finally, scaling laws for Skyrmions will be presented.
