Growth of Single-Crystal Garnets by a Modified Pulling Technique

Abstract

Yttrium iron garnet has been grown by a modified pulling technique where a BaO·0.6B2O3 solvent is used instead of the pure melt. Excess garnet is taken into solution at the hotter bottom of the crucible and deposited on the cooler seed at the surface. The rate of seed rotation, the rate of withdrawal from solution, and the orientation dependence are discussed.
