Fotoferroelektryczne zjawiska w monokryształach $(Ba, Sr) Nb_2O_6$

Abstract

Influence of illumination on phase transition temperature, on dielectric permittivity and on pyro currents in $Ba_xSr_{1-x}Nb_2O_6$ was studied. Dependence of photoelectretic charge density on temperature in the region of phase transition was also investigated.
