Abstract
Single crystal X-ray diffraction analysis was performed on crystals wi th composition Ba1-deltaSrdeltaMgF4 (delta less than or equal to 0.55) . The complete structure was analyzed for single domain crystals with nominal (refined) values of delta = 0.25 (0.27(2)) and 0.5 (0.55(2)). Interatomic distances vary in a characteristic manner, when smaller st rontium ions replace the barium ions. Optical studies of Sm(II) doped samples show significant inhomogeneous line broadening and confirm the disorder on the Ba site. Copyright (C) 1997 Elsevier Science Ltd.
