1. Materials that exhibit spontaneous electric polarization that can be reversed by applying an external electric field; used in capacitors, sensors, and memory devices.
Usage: technical; plural form; singular is ferroelectric; commonly used in materials science and physics

Examples

• Ferroelectrics are essential components in modern electronic devices such as smartphones and computers.
• The research team studied the properties of ferroelectrics to improve capacitor performance.
• Ferroelectrics can retain their polarization even after the external field is removed.
• Scientists are developing new ferroelectrics with higher transition temperatures for industrial applications.
• The spontaneous polarization in ferroelectrics makes them valuable for sensor technology.
