Perovskite CaTiO 3 as an incipient ferroelectric
Abstract
Dielectric measurements were performed in CaTiO 3 ceramic samples at frequencies from 10 Hz-1 MHz and at temperatures between 4.2 and 300 K. The dielectric constant increases with decreasing temperature and saturates at low temperatures. According to this behavior, CaTiO 3 has been classified as an incipient ferroelectric or a quantum paraelectric similar to SrTiO 3, KTaO 3 and TiO 2.
