The existence of domain walls reduces both the spontaneouspolarization and the Curie temperature, and increases the critical size.
畴壁的存在使自发极化和居里温度降低,使临界尺寸增大。
2
The spontaneouspolarization of ferroelectric films was strengthened and then weakened with the increasing of annealing temperature.
此外,随退火温度升高,铁电薄膜的自发极化强度先增强后减弱。
3
The ferroelectricity means the spontaneouspolarization that exists in some materials, and the spontaneouspolarization can change its direction when the external electric field alters.
