…Ferroelectrics generally do not have spontaneous polarization at high temperatures, and as the temperature is lowered, they undergo a phase transition to the ferroelectric phase at a certain temperature. This is called the ferroelectric phase transition. At temperatures above this phase transition point (sometimes called the Curie point), the dielectric constant increases with decreasing temperature according to the Curie–Weiss law, and diverges at the phase transition point. … *Some of the terminology that refers to "ferroelectric phase transition" is listed below.

…強誘電体は高温では一般に自発分極をもたず,温度を下げていくと,一定の温度で強誘電相へ相転移する。これを強誘電相転移という。この相転移点(キュリー点ということがある)以上の温度では,誘電率は温度が下がるとキュリー=ワイスの法則に従って増大し,相転移点で発散する。… ※「強誘電相転移」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
