Abstract
Some ferroelectric and crystallographical properties of the compound are presented. The compound represents a new structure with the unit cell consisting of one layer and five perovskite layers. From -196° to +580°C, a maximum in the real part of the dielectric constant was observed at 329°C. No thermal hysteresis was observed within the precision of ±2°C. A remanent polarization of 2× coul/ and a coercive field of 10 kv/cm were observed at room temperature.
