Abstract
Far-infrared reflection spectra and results of dielectric measurements of SrTiO3 single
crystal doped by neodymium are presented in the paper. Dielectric investigations were conducted at
temperature range from 25 K to room temperature for the test frequency 1MHz. The numerical
analysis of the far-infrared reflection spectra made using a fitting procedure based on factorized
form of the dielectric function. The results for SrTiO3: Nd are compared with those for pure
crystal. The lowest-frequency phonon mode is found to be strongly influenced by presence of
neodymium ions in SrTiO3 single crystal.
