Dielectric hysteresis properties of undoped and dysprosium-doped potassium vanadate have been studied in the temperature range covering their transition points. The coercive field of these materials was measured by the hysteresis loop method. It is observed that the coercive field of KVO3 doped with Dy2O3 at different concentrations (0 to 3 mol%) is remarkably dependent on doping concentration. It is also seen that undoped KVO3 shows ferroelectric behaviour up to 320°C while Dy2O3-doped KVO3 samples show ferroelectric behaviour up to 380°C for all concentrations.
