Abstract
The dielectric properties such as the real € I and imaginary E" parts of the complex permittivity and the spontaneous polarization P of ceramic Pb(Fe Ta 10 with the diffuse 3hase transition (DPT)ld&el&as&ed under pressures up to Gkbar. The value of & ' shows a broad maximum at a temperature T (mean Curie temperature). As the pressure increases ,(Fm of the maximum in E ' ( E ' ) and the value of tomax decrease,and the shapema? the maximum in E' around T becomes broader. ?he pressure coefficiert of T ismabout -3.PK/kbar. ?he temperature and presyure dependence of f.' and P o f a phenomenological theory usbg statistical treatments based on a gsussian distribution of the local Curie temperature. The value o f the standard deviation rdescriking the intensity of the DPT is 25K and increases with increasirg pressure. is explained in terms
