Surface Effects On Wetting and Layering Transitions
Wetting phenomena plays an interesting role in the technological development of materials. Recently, much attention has been directed to the study of magnetic solid films. To understand, theoretically, the effect of surface on wetting and layering transitions in these systems, we will give in this chapter a presentation of several relevant recent theoretical works realized on wetting and layeri...
متن کاملSurface coupling effect on wetting and layering transitions
The effect of both surface coupling Js and surface magnetic field Hs on the dependency of the layering temperature TL as a function of the thickness N , of a spin−1/2 Ising film is studied using mean field theory. It is found that for Js greater than a critical value (Jsc = 1.30), the layering temperature decreases when the film thickness N increases for any values of Hs. While, for Js < Jsc, t...
متن کاملThe effect of the inhomogeneity of substrate on layering transitions
We study the substrate inhomogeneity effect on the wetting of a spin-1/2 Ising ferromagnetic film in an external magnetic field H, using Monte Carlo simulations. It is found the inhomogeneity leads to the formation of islands of positive spins in each layer. However, depending on the values of H, for a fixed surface magnetic field Hs, each layer exhibits three different phases; totally wet (TW)...
متن کاملLayering transitions at grain boundaries
We review various simplified models that have been advanced to describe layering (complexion) transitions at grain boundaries in multicomponent solids. In particular, we first outline lattice-gas, off-lattice atomistic and thermodynamic models that have been employed to investigate phase-like behavior at segregated grain boundaries. The results of these investigations are summarized in the form...
متن کاملA Monte Carlo study of random surface field effect on layering transitions
The effect of a random surface field, within the bimodal distribution, on the layering transitions in a spin-1/2 Ising thin film is investigated, using Monte Carlo simulations. It is found that the layering transitions depend strongly on the concentration p of the disorder of the surface magnetic field, for a fixed temperature, surface and external magnetic fields. Indeed, the critical concentr...
