Ferroelectricity — is a property of certain materials which possess a spontaneous electric polarization that can be reversed by the application of an external electric field.[1][2] The term is used in analogy to ferromagnetism, in which a material exhibits a… … Wikipedia
Dielectric — A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material, as in a conductor, but only slightly shift from their … Wikipedia
Ionic polarization — In chemistry, ionic polarization is polarization which is caused by relative displacements between positive and negative ions in ionic crystals (for example, NaCl).If crystals or molecules do not consist of only atoms of the same kind, the… … Wikipedia
Ferroélectricité — On appelle ferroélectricité la propriété selon laquelle un matériau possède une polarisation électrique à l état spontané, polarisation qui peut être renversée par l application d un champ électrique extérieur. La signature d un matériau… … Wikipédia en Français
