Abstract
The mechanoactivation of ferroelectric materials with perovskite structure is performed. Structural changes of the ferroelectric materials after mechanoactivation based on X-ray absorption spectra (XAFS) and X-ray diffraction data (XRD) are studied. The Fourier analysis of EXAFS spectra allows quantitative estimates to be obtained for the local atomic structure of the investigated materials after activation. The effect mechanoactivation has on permittivity in a wide range of frequencies and temperatures is considered.
