Abstract
- Dielectric and pyroelectric properties of the mixed crystals system, (CH3NH3)5Bi2Cl11x (0 < x < 1), were systematically investigated. Temperature dependence of ξc in the vicinity of ferro-paraelectric phase transition was measured for the crystals with x = 0.91, 0.44, 0.27 0.05 in the frequency region 1 kHz-1 MHz. The substitution of bromine atoms by chlorine ones and vice versa, drastically reduces the magnitude of ξc at Tc but does not influence on the temperature behaviour of the spontaneous polarization.
