Abstract

Large stoichiometric MgAl2O4 spinel single crystals of high crystalline perfection have been grown by the Czochralski method. By means of X-ray diffraction topography the dislocation arrangement, Burgers vector directions and glide planes were investigated in relation to crystal growth conditions. Fast cooling rates generated prismatic dislocation hexagons in the central region of as-grown crystals. For the first time a new glide system in spinel following {311} planes was observed.
