domain growth

[dō′mān ‚grōth]
(solid-state physics)
A stage in the process of magnetization in which there is a growth of those magnetic domains in a ferromagnet oriented most nearly in the direction of an applied magnetic field.

Moreover, increasing investment for the domain growth is expected to offer opportunities in the market.
This approach allowed distinguishing five subsequent stages of domain growth: (1) discrete switching (appearance of isolated nanodomains) (Figure 1(a)), (2) domain ray growth (Figure 1(b)), (3) domain merge leading to formation of fish-bone structure (Figure 1(c)), (4) formation of stripe domains (Figure 1(d)), and (5) widening of stripe domain by sideways domain wall motion (Figure 1(e)).
All obtained results have been explained in terms of kinetic approach based on analogy of domain growth with first-order phase transition.
Stages of domain growth: (a) discrete switching, (b) domain ray growth, (c) domain merge, (d) formation of stripe domains, and (e) widening of stripe domain.

The process is also called phase-ordering dynamics, or domain growth or coarsening, and the study of it requires tools from a number of the physical sciences.
Billon and Haudin [19-21] presented a generalized Evans approach [5], in which they attempt to consider position and time dependence of nucleation rate and time-dependence of domain growth rate.
The model consists of three parts: primary nucleation model, domain growth model and lamellae director model.
Effects of external forces on morphological formation are included in the nucleation model for determining the formation and spatio-temporal evolution of nuclei, as well as in the proposed envelop equation of domain growth model for determining the spherulitic growth velocity.
The proposed envelop equation of domain growth is linked with the nucleation model and the elastic curvature energy equation of the lamellar director field to perform cross-scale modeling.
In order to set up a physical morphological model of domain growth, a generalized Langevin equation [58] is introduced:
