Using the methods of radiospectroscopy (EPR, NMR) to study the nature of the defect structure of solid solutions based on lead zirconate titanate (PZT).

The nature of intrinsic and impurity point defects in lead zirconate titanate (PZT) ceramics has been explored. Using electron paramagnetic resonance (EPR), nuclear magnetic resonance (NMR), and X-ray photoelectron spectroscopy (XPS) methods, several impurity sites have been identified in the materials, including the Fe(3+)-oxygen vacancy (VO) complex and Pb ions. Both of these centers are incorporated into the PZT lattice.

Ambience-sensitive optical refraction in ferroelectric nanofilms of NaNbO.

Optical index of refraction is studied by spectroscopic ellipsometry in epitaxial nanofilms of NaNbO with thickness ∼10 nm grown on different single-crystal substrates. The index in the transparency spectral range ( ≈ 2.1 - 2.
