This article is a brief review of coarsening phenomena occurring in systems where quenched features—such as random field, varying coupling constants or lattice vacancies—spoil homogeneity. We discuss the current understanding of the problem in ferromagnetic systems with a non-conserved scalar order parameter by focusing primarily on the form of the growth law of the ordered domains and on the scaling properties.
Cet article constitue un bref survol des phénomènes de coarsening qui se produisent dans des systèmes où des inhomogénéités gelées, telles que champs aléatoires, constantes de couplage variables ou lacunes de réseau, détruisent l'homogénéité. Nous discutons la compréhension que l'on a actuellement de ce problème dans les systèmes ferromagnétiques avec un paramètre d'ordre scalaire non conservé, en se concentrant d'abord sur la loi de croissance des domaines ordonnés et sur les propriétés d'échelle.
