Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Some new possibilities of determining the gaussian distribution of Curie-
Weiss temperatures and relaxation times in relaxors and in ferroelectrics
with a diffused phase transition are presented in this paper. The method
of determining the width of gaussian distribution of Curie-Weiss temperatures with the use of the reciprocal of dielectric permittivity on normalized
plots is applied to solid solution Ba(Ti₁₋xSnx)O₃. The method of estimating
the gauss-logarithmic distribution of relaxation times based on normalized
plots is proposed for relaxors. It is shown that the Vogel-Fulcher behaviour
of real and imaginary parts of the dielectric permittivity in PMN is caused
by gauss-logarithmic distribution of relaxation times and by its temperature
dependence. |
