A collection of 505 papers on false or unconfirmed ferroelectric properties in single crystals, ceramics and polymers

Abstract

This collection presents 505 papers on ferroelectricity in single crystals, ceramics and polymers in which pointed or elliptical hysteresis loops would testify to their ferroelectric properties. In some papers, the authors ensure that ferroelectricity can occur even in materials that do not have a polar axis of symmetry.

Keywords
