Abstract :
The pressure dependence of relative permittivity for various electric fields at -20°C and -35.5°C of antiferroelectric cupric formate tetrahydrate is calculated and interpreted in terms of a phenomenological theory. The permittivity of the antiferroelectric phase decreases with increasing pressure, and the permittivity of the induced phase decreases with increasing electric field
