Obvious changes have been observed in the Hg+-implanted SBN crystals doped with rare-earths and alkaline metal by X-ray diffraction and temperature-dependence measurements of the dielectric constant
namely
(1) decrease in intensities of X ray diffraction
(2) anomaly of the diffraction patterns for Hg+-implanted PrSBN
and (3) increase in critical exponents of the dielectric constants.
