Abstract
The surface structures of {110} and {211} faces of yttrium-iron garnet (YIG) and {0001} and {10-11} faces of magnetoplumbite, both synthesized by by the flux method, were studied in detail, using a phase contrast and an interferometric microscope. Growth spirals were widely observed on both crystals, from which it was concluded that the mechanism of crystal growth in the system of flux synthesis is fundamentally similar to that in the crystallization from vapour or solution. The morphology of interlaced spirals observed on the {0001} faces of magnetoplumbite was fully accounted for from the geometry of its crystal structure.
