Abstract
The dielectric hysteresis property of undoped and Gd2O3-doped potassium vanadate and lithium vanadate has been investigated in the temperature range covering their transition points. The hysteresis loop method has been used for coercive field measurements. The coercive field of Gd2O3-doped KVO3 and LiVO3 increases for 0·025, 0·05, and 0·1 mol %, however, it decreases for 0·5, 1 and 3 mol % of Gd2O3. It was found that the Curie temperatures of KVO3 and LiVO3 remain the same for various concentrations of Gd2O3.
