Crystal growth of Ca3−xYxMn2Ge3O12 and phase relations in the PbOB2O3GeO2 based melts

The bulk crystals of Ca3−xYxMn2Ge3O12 garnets were grown on a seed from the PbOB2O3GeO2 based melts, where the primary crystallization field of garnets was found. The saturation temperatures of the melts were determined before each growth run. The dependence of Y incorporation into the crystals versus the melt composition was also evaluated.
