A method for the single crystal growth of Yttrium Iron Garnet (YIG) in a PbO/PbF 2 /B 2 O 3 flux mixture with a melt cooling rate of 1–2.5 °C/h is described. In order to keep constant the crystal stoichiometry as well as its specific structural and magnetic properties at such high rates of the cooling process, a previously sintered polycrystalline garnet has been used as raw material. The YIG single crystal quality was checked‐up by metallographic analysis, X‐ray diffraction, SEM, and magnetic susceptibility measurements.
