Critical exponents of the order parameter of diffuse ferroelectric phase transitions in the solid solutions based on lead germanate: studies of optical rotation
Autor: Adamenko, D. I., Vlokh, R. O.
Publikováno v: Condensed Matter Physics, 2022, vol. 25, No. 4, 43703
In this work we show that the critical exponents of the order parameter (CEOPs) of diffuse ferroelectric phase transitions (DFEPTs) occurring in lead germanate-based crystals can be determined using experimental temperature dependences of their optic

Autor: Krupych, O., Vasylkiv, Yu., Adamenko, D., Vlokh, R., Vlokh, O.
Publikováno v: Ukr. J. Phys. Opt. 2006 7 171-178
We present the results of studies for magnetogyration (MG) effect in (Ga0.3In0.7)2Se3 and SiO2 crystals performed with the small-angular polarimetric mapping technique. It is shown that the MG effect magnitude is comparable with the experimental erro
