GROWING THE MONOCRYSTALS OF THE GALLIUM GARNETS WITH PARTIAL SUBSTITUTE OF LUTECIUM AND YTTERBIUM FOR GALLIUM IONS

The work is devoted to the creation of the new gallium garnets with the isomorphic replacement of the gallium ions by the more heavy rare ions and to the determination of the optimum conditions of its growing. The crystals in the work were grown by the method of Chokhralsky. The crystals have been examined with the aid of the roentgenophase analysis, roentgenofluorescent analysis and optic spectroscopy. For the first time, using the method of Chokhralsky, the monocrystals lanthanium-ytterbium-gallium and gadolinium-ytterbium-gallium garnets, and several new compositions of gadolinium-lutecium-gallium garnet have been received. The optimum compositions and the conditions of these crystals growth have been offered. Developed has been the new way of struggle against the spiral growth phenomenon. The new automated control system of the gallium garnets growth has been created. The results of the work have been used in the Institute of Common Physics of the Russian Academy of Sciences. They also can find application on the different enterprises of the electronic technique, specializing on the growth of the oxide monocrystalsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
