The dielectric properties of pure and doped with different concentrations of Nd₂O₃ ferroelectric KVO₃ and LiVO₃, have been studied by using a digital LCR meter VLCR-7 at fixed frequency (1KHz) in the region of their phase transition. The dielectric constant shows a sharp peak at the phase transition in all the compositions. The dielectric constant is found to increase significantly, when dopant concentration is increased up to 0.5 mol % Nd₂O₃, however decreases for higher concentrations. The Curie temperature of all the samples decreases with increase in Nd concentration.
