摘要：
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. © 1990.
