摘要：

Measurement of the dielectric constant and optical observation of domain structure in (CH3NH3)5Bi2Cl11 have been carried out in the temperature range including 170 K, which has been regarded as a transition temperature. No indication of any phase transition was obtained near 170 K. Temperature dependence of the dielectric constant in this temperature range has been explained applying the Landau theory.
