short-range order

As with all amorphous solids, some short-range order can be observed.

The stability of the short-range order phase is investigated.

If the spin is integer then only short-range order is present.

This incompatibility of the preferred short-range order with a global packing is termed `frustration'.

The crystal structure shows some short-range order, but linkages between islands are fully disordered.

As with all glassy materials, some short-range order can be observed, but there is no long-range pattern of atomic positions.

Depending on how the correlations decay with distance, one speaks of long-range order or short-range order.

Since the short-range order is similar in glasses and crystals, the electronic energies should be similar in these two states.

However, due to chemical bonding characteristics glasses do possess a high degree of short-range order with respect to local atomic polyhedra.

They do however show a certain degree of short-range order, depending on their density and on the strength of the interaction between particles.

In neat liquids and solutions there is little short-range order, and at any instant different molecules are under the influence of randomly-differing local environments.

Another set of diffuse spots in the scattering pattern may be due to short-range order of Cs and Na.

The electrons will only be sensitive to the short-range order in the glass since they do not get a chance to scatter from atoms spaced at large distances.

The Penn theory for materials with tetrahedral short-range order was applied and the absorption coefficient of ion-implanted GaAs is also reported.

Other areas of ongoing interest include polarised neutron spectrometry, diffuse X-ray scattering to explore short-range order and condensed matter physics with a focus on magnetism.

Polarisation analysis can be used to separate magnetic scattering from nuclear scattering, providing unambiguous data for determination of atomic and magnetic short-range order.

Short-Range Order in a Binary Ising Lattice", Phys."

Within this framework, "domains" exhibiting various degrees of short-range order become the building blocks of both metals and alloys, as well as glasses and ceramics.

The nearest neighbour longitudinal correlation is estimated to be . A short-range order parameter, the chirality, is defined and estimated for the infinite lattice.

A solution containing an aqua ion does not have the long-range order that would be present in a crystal containing the same ion, but there is short-range order.

One such material, amorphous indium-zinc-oxide maintains short-range order even though crystallization is disrupted by the difference in the ratio of oxygen to metal atoms between In2O3 and ZnO.

In the region of short-range order the off-diagonal (AB) time correlation function is negative but otherwise shows similar behaviour to the diagonal one, although as the transition temperature is approached n varies more rapidly.

A number of speculative mechanisms have been advanced to counter this, the most widely discussed being water memory, though this is now considered erroneous since short-range order in water only persists for about 1 picosecond.

The quasi-chemical theory and the quasi-lattice theory are discussed with a view to obtaining information about concentration fluctuations, SCC(0), and the short-range order parameter, α1, for regular and compound-forming molten alloys.

Structurally, most systems exhibit a clear instability toward the formation of periodic domains of relatively short-range order Above a critical amplitude of oscillation, plastic deformation is the primary mode of structural rearrangement.
