Abstract
Experiments were made to prepare yttrium iron garnet (Y3Fe5O12) single crystals in molten YF3-PbF2 solutions. The solubilities of Y2O3 in YF3 were obtained by differential thermal analysis, and those of Fe2O3 in PbF2 in air by chemical analysis of quenched specimens.Mixtures of Y2O3 and Fe2O3 were dissolved in YF3-PbF2 solutions at 1300°-1350°C and then the solutions were cooled at the rate of 4-10°C/hr to prepare yttrium iron garnet single crystals.Spacings of these crystals were compared with those of crystals prepared by the other methods.
