Abstract
The nature of cation doping in the important optical material lithium niobate has been studied using a combination of X-ray and neutron powder diffraction methods. Samples of nominal composition Li1-xMgxNbO3 (x = 0.1, 0.2, 0.3) were studied. Magnesium was found to substitute exclusively at the Li site, with concommitant Li vacancies, and with no deviation from stoichiometry at the Nb position, i.e. [Li1-xMgx/2][Nb]O-3. This is the first detailed structural study of doped lithium niobate by diffraction methods and supports previous models obtained by local structural techniques and computational methods.
