Popis:	Complex studies of the optical and structural properties and the elemental composition of a series of yttrium iron garnets (YIG) grown from flux have been performed with due regard for the crystallographic orientation of the platelets. It has been established that the presence of Mn, Ba, and V microimpurity ions at a level of a few thousandths of a percent can play a stabilizing role in the synthesis of perfect crystals with the garnet structure. The criterion of the quality of the grown crystals is formulated as the ratio of the total number of Y and Fe cations to the number of oxygen anions (in wt %).
