The floating zone growth of magneto‐optical crystal YFeO 3 has been investigated. The polycrystalline feed rod was prepared by a pressure of 250MPa and sintering at about 1500°C. A crack‐ free YFeO 3 single crystal has been successfully grown. The crystal preferred to crystallize along <100> direction with about 10° deviation. The X‐ray rocking curve of the crystal has a FWHM of 24 arcsec, confirming the high crystal quality of the sample. The (100) plane was etched by hot phosphoric acid and the dislocation density was about 10 4 /cm 2 . A thin outer layer with Y 2 O 3 ‐rich composition was found at the periphery of as‐grown crystals, which was attributed to the Fe 2 O 3 evaporation during growth. (© 2007 WILEY‐VCH Verlag GmbH & Co.
