摘要：

Dielectric properties of Ca2Ba(C2H5CO2)6 single crystals have been studied at hydrostatic pressure of about 0.9 kbar. It has been found that the high-pressure phase V is ferroelectric. D-E hysteresis loop at 60 Hz is observed only on annealed specimens, but not on as-grown crystals. It is suggested that the ferroelectric phase V of Ca2Ba(C2H5CO2)6 corresponds to those well-known ferroelectric phases II of Ca2Sr(C2H5CO2)6 and Ca2Pb(C2H5CO2)6 which are realized at atmospheric pressure. © 1979, THE PHYSICAL SOCIETY OF JAPAN.
