magnetocrystalline anisotropy energy
1Magnetocrystalline anisotropy — is the dependence of the internal energy of a ferromagnet on the direction of its magnetization. As a result, certain crystallographic directions are preferred directions, or easy axes, for the magnetization. It is a special case of magnetic… …
2Anisotropic energy — is energy that is directionally specific. The word Anisotropy means directionally dependent , hence the definition. The most common form of anisotropic energy is Magnetocrystalline Anisotropy, which is commonly studied in ferrimagnets. In… …
3Magnetic anisotropy — is the direction dependence of a material s magnetic properties. In the absence of an applied magnetic field, a magnetically isotropic material has no preferential direction for its magnetic moment while a magnetically anisotropic material will… …
4Magnetic domain — Several grains of NdFeB with magnetic domains made visible via contrast with a Kerr microscope. A magnetic domain describes a region within a magnetic material which has uniform magnetization. This means that the individual magnetic moments of… …
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… …
6Domain wall — A domain wall is a term used in physics which can have one of two distinct but similar meanings in magnetism, optics, or string theory. These phenomena can all be generically described as topological solitons which occur whenever a discrete… …
7Magnetic domains — A magnetic domain describes a region within a material which has uniform magnetization. This means that the individual moments of the atoms are aligned with one another. In most materials, domains do not naturally exist. The materials have to be… …
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… …
9Exchange bias — or exchange anisotropy occurs in bilayers (or multilayers) of magnetic materials where the hard magnetization behavior of an antiferromagnetic thin film causes a shift in the soft magnetization curve of a ferromagnetic film. The exchange bias… …
10Ferromagnetism — 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… …
