Easy growth directions

Fig. 27. Temperature dependence of the width of domain stripes as measured by Shono et al. (2000) for the Gao.957Mno.043 As film with the easy axis along the growth direction (full squares). Computed domain width is shown by the solid line. The dashed line is computed assuming that the parameter Ac (eq. (20)) is by a factor of...

The coke-former aromatic hydrocarbons listed in Table 4.1 and shown in Fig. 4.2, i.e., naphthalene, einthracene, and acenaphtalene, are linear with a coplanar structure that has no preferred growth direction. This structural feature and the formation of a mesophase mentioned in Sec. 2.3 are the major factors in the easy conversion of theturbostratic structure into well-ordered graphite planes.1 1... 

As described in the introduction, OD ceria nanoparticles are easy to obtain because the cubic phase structure has no special favorite growth direction. 

The single crystal phases in eutectics often grow preferentially along well-defined crystallographic directions that are not necessarily the directions of easy growth of the components but which correspond to structures with minimum interfacial energy. In fact, eutectic stability and most of the properties of the structures depend on the interface properties because the interfacial surface is very large (Llorca Orera, 2006). 

The extension of generic CA systems to two dimensions is significant for two reasons first, the extension brings with it the appearance of many new phenomena involving behaviors of the boundaries of, and interfaces between, two-dimensional patterns that have no simple analogs in one-dimensional systems. Secondly, two-dimensional dynamics make it an easy (sometimes trivial) task to compare the time behavior of such CA systems to that of real physical systems. Indeed, as we shall see in later sections, models for dendritic crystal growth, chemical reaction-diffusion systems and a direct simulation of turbulent fluid flow patterns are in fact specific instances of 2D CA rules and lattices. 

R. E. McCarley In response to the first question, it should be easy to predict those metal orbitals which would protrude from the 001 and 002 faces of NaMo4C>6, i.e. those faces normal to the direction of chain growth. However, up to the present time we have not considered such questions because of our generally poor understanding of bonding details in these extended systems. 

Magnetization of a material. Initially, magnetization increases by growth of favorably oriented domains. At high fields, the direction of magnetization rotates out of the easy direction.
