Abstract
The dielectric constant epsilon' as well as the dielectric loss tan de lta on a pellet of powdered (CH2)(8)(NH3)(2)MCl(4) (M = Mn and Fe) are measured as a function of temperature. epsilon' and tan delta reveal more than one peak. One of these peaks is due to a structural phase tr ansition and the others are due to order-disorder acid chain melting t ransitions. Electronic, ionic, and rotational polarization are taken i nto consideration.
