Abstract

We discuss theoretically the isotope effects on phase transition temperature T-c and generalized force constant k(f) in perovskite-type ferroelectric. We give the result of our calculation on the reduced force constant of the soft optic phonon with quantum-mechanical electron-phonon interaction model at finite temperature.
