Abstract

PURPOSE:To obtain the titled single crystal with scarce occurrence of crack and little crystal dislocation, etc., having uniform composition, by growing a single crystal from a mixed melt of Nd2O3 and Ga2O3 of congruent composition contg. Nd2O3 in a specified molar ratio. CONSTITUTION:The mixed melt of Nd2O3 and Ga2O3 of congruent composition contg. 37.6-37.8mol.% Nd2O3 is prepared. Neodymium.gallium.garnet single crystal is obtd. by pulling up a single crystal from the mixed melt by Czochralski method. Since a single crystal having constant composition at any part of the crystal is obtd. by this process, a single crystal wafer having large diameter such as 4 in can be easily produced and the single crystal obtd. is suitable for a substrate for magnetic bubble, a substrate for optical use, etc.
