crystalline anisotropy
1Anisotropy — (pronounced with stress on the third syllable, IPAEng|ˌænaɪˈsɒtrəpi) is the property of being directionally dependent, as opposed to isotropy, which means homogeneity in all directions. It can be defined as a difference in a physical property… …
2Texture (crystalline) — In materials science, texture is the distribution of crystallographic orientations of a polycrystalline sample. A sample in which these orientations are fully random is said to have no texture. If the crystallographic orientations are not random …
3Seismic anisotropy — is a term used in seismology to describe the directional dependence of seismic wavespeed in a medium (rock) within the Earth. Crustal Anisotropy In the Earth s crust, anisotropy may be caused by aligned microcracks, shear fabric, layered bedding… …
4Superparamagnetism — is a form of magnetism. A superparamagnetic material is composed of small ferromagnetic clusters (e.g. crystallites), but where the clusters are so small that they can randomly flip direction under thermal fluctuations. As a result, the material… …
5Magnetische Anisotropie — beschreibt die Tatsache, dass magnetische Materialien eine Vorzugsrichtung oder Vorzugsebene für die Magnetisierung aufweisen können. Das Maß dafür ist die magnetische Anisotropieenergie, die als die Arbeit definiert ist, die benötigt wird, um… …
6Picosecond ultrasonics — When an ultrashort light pulse (duration: 100 fs, energy …
7Liquid crystal — Schlieren texture of liquid crystal nematic phase Liquid crystals (LCs) are a state of matter that have properties between those of a conventional liquid and those of a solid crystal.[1] For instance, an LC may flow like a liquid, but its… …
8magnet — /mag nit/, n. 1. a body, as a piece of iron or steel, that possesses the property of attracting certain substances, as iron. 2. a lodestone. 3. a thing or person that attracts: The park was a magnet for pickpockets and muggers. [1400 50; late ME… …
9Ferromagnetism — Not to be confused with Ferrimagnetism; for an overview see Magnetism A magnet made of alnico, an iron alloy. Ferromagnetism is the physical theory which explains how materials become magnets. Ferromagnetism is the basic mechanism by which… …
10Crystallization of polymers — Spherulites viewed between crossed polarizers in an optical microscope. Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae,… …
