Abstract
In this paper a summary is given on the reproducible preparation of large, nearly defectless yttrium iron garnet single crystals (YIG) grown in fluxes by slowly cooling with accelerated crucible rotation (ACRT) and local bottom cooling. The surface morphology of the growth faces is discussed with regard to the growth mechanism. By different methods the crystals are characterized regarding their lattice defects (impurities, growth striations, dislocations, inclusions). Ferromagnetic resonance measurements in the X‐band at polished, inclusionsfree discs show that the linewidth ΔHof any crystals from different runs are less than 0.45 Oe.Keywords
