Abstract :
An experimental relation is found between the pyroelectric and electrooptic coefficients of several ferroelectric materials. The physical basis of this relation is explained using Garrett´s anharmonic oscillator model, and the pyroelectric coefficients of Sr0.25Ba0.75Nb2O6, Sr2NaNb5O15,Ba2NaNb5O15, KSr2Nb5O15, K3Li2- Nb5O15, and Ag3AsS3are predicted from the known electrooptic coefficients.
