Influence of commensurability energy on the incommensurate structure dynamics in [N(CH3)4]2CuCl4 crystal — •Ivan Karpa — Ivan Franko Lviv National University, Department of Electronics, Non-linear Optics Chair
Investigations of sample size of [N(CH3)4]2CuCl4 crystal influence on the optical birefringence is studied. It has been shown that decreasing of crystal size is accompanied by increasing of commensurability energy. It is seen in the increasing of incommensurate-commensurate phase transition temperature and expansion of temperature interval of metastable phase existence. It has been set that decreasing of crystal size is accompanied by decreasing of incommensurability parameter. It is seen in the increasing of parent-incommensurate phase transition temperature.
