Abstract

Abstract Data are presented on dielectric properties of Rb2CoCl4 crystals. A wide tail of enhanced permittivity extends into the ferroelctric phase. It shows a relaxation in the MHz region with a wide distribution of relaxation times. On lowering temperature, the decrease in permittivity is accompanied by dielectric softening as revealed by decreasing mean relaxation frequency.
