Studying of dielectric spectra of YCu0.15Mn0.85O3 solid solution with the use of complex conductivity

This work presents the results of studying the electrophysical properties of the YCu0.15Mn0.85O3 solid solution in the range of temperatures of T= 26-400 degrees C and frequency range of f =10(2)-10(5) Hz. A model description of the revealed dispersion of dielectric parameters in the material is made. The nonclassical modified Havriliak-Negami model written for complex electrical conductivity was used as an approximation model. It is shown that the application of this model almost exactly describes the frequency behavior of the dielectric constant epsilon'/epsilon(0)(f), the dielectric loss tangent tg delta(f) as well as the real and imaginary parts of complex conductivity gamma'(f) and gamma ''(f). The results of this work are an important step in identifying the opportunities and understanding the applications of this model.

Automated summary

This study investigates the electrophysical properties of the YCu0.15Mn0.85O3 solid solution and proposes a nonclassical modified Havriliak-Negami model to describe the observed dispersion of dielectric parameters. The results demonstrate that this model accurately represents the frequency behavior of the complex conductivity and dielectric constant of the material.
