Pyroelectric properties of Gd-doped and undoped potassium vanadate and lithium vanadate investigated in the temperature range covering their transition points show sharp increase at Curie temperature for undoped and for 0·025, 0·05, 0·1 mol% Gd2O3-doped, but no remarkable peak at Curie temperature for 0·5, 1, 3 mol% Gd2O3-doped KVO3 and LiVO3. The Curie temperature of all the samples remains the same for various concentrations of Gd.
