摘要
The internal friction spectra of an amorphous thin-film bismuth ferrite deposited on a silicon substrate were studied. The temperature dependence of mechanical losses near the glass transition temperature revealed a wide maximum of internal friction associated with alpha-relaxation of the amorphous structure. In this temperature region, two linear sections in the lnQ(-1) vs (1/T) dependence are observed with an intersection point at the glass transition temperature. According to the results of low-and high-temperature internal friction investigation of the amorphous bismuth ferrite in the alpha-relaxation region, the values of the migration energy and the formation energy of vacancies-like defects were estimated, which are equal to E-m = 0.80 +/- 0.08 eV and E-v = 0.88 +/- 0.08 eV, respectively.
