Abstract
The strongly enhanced domain wall response in the ferroelectric phase of pu
rified Rb2ZnCl4 is studied at low ac-field level E((ac))less than or equal
to 0.3V/cm. In the incommensurate-commensurate transition range, the therma
l hysteresis of the imaginary part epsilon"(T) of permittivity is much bigg
er than those of epsilon'(T). At low frequencies, an anomaly of epsilon"(T)
is observed at T approximate to 170K.
