Abstract
The results of examination of AC dependences of capacitance and dielectric loss tangent of sillenite Bi12TiO20 crystals doped with ruthenium on frequency are presented. Non-Debye dispersion of dielectric coefficients is found in the frequency interval of 5 × 102–105 Hz, and a resonance phenomenon is observed. Polarization processes in the studied samples are attributed to relaxators associated with metal–oxygen vacancies and structural elements incorporating 6s2 lone-pair electrons.
