Ferroelectricity of Inclusion Compounds of Thiourea with Pyridinium Iodide and Nitrate

open access: yesThe Journal of Physical Chemistry C, 2009
The character of phase transitions in the inclusion compounds of thiourea with pyridinium iodide and nitrate has been analyzed, and a model of ferroelectricity of these compounds has been proposed. Analysis of the temperature dependence of specific heat and intensity of the Bragg peaks has shown that the ferro-paraelectric phase transitions are ...
