The same interactions lead to the observation that the magnetisation in thin hlms changes with him thickness. In thick hlms, of ordinary dimensions, domains form and the magnetic hux is trapped in the him (Figure 12.19a). When the thickness of a him is reduced to below single domain size, the magnetic dipoles align in a parallel direchon in a... 

Though both miscible and immiscible blends are composite materials, their properties are very different. A miscible blend will exhibit a single glass transition temperature that is intermediate between those of the individual polymers. In addition, the physical properties of the blends will also exhibit this intermediate behavior. Immiscible blends, on the other hand, still contain discrete phases of both polymers. This means that they have two glass transition temperatures and that each represents one of the two components of the blend. (A caveat must be added here in that two materials that are immiscible with very small domain sizes will also show a single, intermediate value for Tg.) In addition, the physical properties... 

The ordering of liquid crystalline phases is extensive on the molecular scale. In fact, the self-assembly characteristic as possessed by lipids (amphiphiles) is the basic building feature in LCs. This order extends up to the entire domain size, which may be on the order of micrometers (pm), but usually does not extend to the macroscopic scale as often occurs in classical crystalline solids. However, some techniques (such as the use of boundaries or an applied electric field) can be used to enforce a single ordered domain in a macroscopic LC sample. The ordering in an LC might extend along only one dimension, with the material being essentially disordered in the other two directions.
