Brit.

/ˌfɛrəʊᵻˈlɛktrɪk/, U.S.

/ˌfɛroʊəˈlɛktrɪk/,

/ˌfɛroʊiˈlɛktrɪk/

Origin: Formed within English, by compounding. Etymons: ferro- comb. form, electric adj.

Etymology: < ferro- comb. form + electric adj., after ferromagnetic adj., on account of the analogous properties (although ferroelectric materials do not necessarily or commonly contain iron).

Physics.

A. adj.

Of an object or substance: having a permanent electric polarization that can be changed or reversed by the application of an electric field. Also: of or relating to this property or phenomenon.Ferroelectric materials, which are used in capacitors, have very large permittivities and exhibit hysteresis (delay) between the applied field and the resulting polarization. Their crystals contain domains of parallel electric dipoles.

ferroelectric1935

1935 H. Mueller in Physical Rev. 47 180 The dielectric properties of Rochelle salt..are analogous to the ferromagnetic properties near the Curie point. This fact justifies the use of Eq. (7) for the ‘ferro-electric’ temperature range.

1955 Sci. Amer. June 96/2 The material used in the experimental ferroelectric memory systems is barium titanate.

1965 Wireless World July 339/1 (caption) Method for scanning an infra-red beam, using a ferroelectric prism.

1990 D. Y. Fong et al. in Internat. Joint Conf. Neural Networks II. 131 The ferroelectric LCD has its opacity related only to the electric field applied across the device.

2007 Science 16 Feb. 954/1 There are now 700 ferroelectric materials, many of which are neither hydrogen bonded nor oxides, such as GeTe, SrAlF₅, or SbSI.

B. n.

A ferroelectric substance or object.

1946 Nature 15 June 808/1 As distinct from other known ferro-electrics, barium titanate does not contain hydrogen.

1970 J. Grindlay Introd. Phenomenol. Theory Ferroelectr. i. 1 Many ferroelectrics possess a spontaneous dipole moment only in certain temperature ranges.

2005 R. E. Newnham Properties of Materials xvi. 185 Lead zirconate titanate (PZT = PbZr_1₋xTi_xO₃) is a proper ferroelectric that is widely used as a piezoelectric transducer.
