ferroelectric

   Also found in: Dictionary/thesaurus, Wikipedia 0.02 sec.

ferroelectric

Refers to a material that functions similarly to a ferromagnetic material in that it can be polarized into two states. Ferroelectric devices generally do not have any "ferrous" (iron) in them. See F-RAM and ferroelectric capacitor.

ferroelectric [¦fe·rō·i′lek·trik]
(solid-state physics)
A crystalline substance displaying ferroelectricity, such as barium titanate, potassium dihydrogen phosphate, and Rochelle salt; used in ceramic capacitors, acoustic transducers, and dielectric amplifiers. Also known as Rochelle electric; Seignette electric.
