IMPROVED METHOD FOR THE GROWTH OF YTTRIUM-IRON AND YTTRIUM-GALLIUM GARNETS
Journal Article

· Journal of Applied Physics (U.S.)
Large single crystals of yttrium and rare earth iron garnets and yttrium and rare earth gallium garnets were grown from molten solutions of lead oxide and lead fluoride. The crystals are grown by slowly cooling melts from about 1260 deg C to near 950 deg C. Sample compositions are: for YIG, 8 mole % Y/sub 2/O/sub 3/, 22 mole % Fe/sub 2/O/sub 3/, 30 mole% PbO and 40 mole a PbF/sub 2/; for YGaG, 5.8 mole% Y/sub 2/O/sub 3/, 14 mole a Ga/sub 2/O/sub 3/, 39.4 mole % PbO and 40.8 mole % PbF/sub 2/. This metho provides crystals both large in size and of superior quality Best results are obtained when the containing crucible is hotter near its top than at its base since nucleation is thereby reduced.
