Glasslike thermal and dielectric properties of Cd 2 Nb 2 O 7 at low temperatures

Abstract
Thermal and dielectric measurements at low temperatures on ceramic samples of ferroelectric Cd2Nb2O7 and non-ferroelectric CdNb2O6 are reported. The data indicate ordinary Debye behavior for CdNb2O6, but the data for Cd2Nb2O7 suggest glasslike behavior.
