Abstract

The dielectric constant as well as the pyroelectric current for the compounds (CH₂)₉(NH₃)₂FeCl_4–xBr_x (x ═ 0 and 1) are measured in the temperature range including the phase transition points. The effect of replacing Cl^– ions by Br^–-ions on the Puckering and the canting angle of the system is discussed together with the effect of phonon-magon interaction on the dielectric constant.
