摘要：

Angular dependence of the line width of the 93Nb NMR spectrum central transition for LiNbo3 crystal with congruent composition and for the samples with high Mg concentration was experimentally investigated. Having the experimental results compared with the results obtained by computer simulation, it has been concluded that the most probable type of defects in magnesium doped LiNbo3 crystals are (4MgLi2+ + 4VLi) defect complexes when four Li vacancies and three MgLi2+ ions being localized in the seven nearest positions to the central MgLi2+ ion. © 2014-STC Institute for Single Crystals.
