摘　　要：正交钙钛矿结构GdFe03材料是一种新型的磁光材料。采用光学浮区法生长磁光晶体GdFeO3，通过多次试验，生长出的晶体直径达到8mm，长度为50～80mm，晶体截面抛光后未发现明显的夹杂物等缺陷。测试结果证明光学浮区法是生长GdFeO3磁光晶体的有效方法。Gadolinium orthoferrite crystals （GdFeO3） with orthogonal perovskite structure is a novel magneto-optical crystal. The magneto-optical crystal GdFeO3 （gadolinium orthoferrite） was grown by floating zone method. The growth parameters were optimized and GdFeO3 single crystal was prepared with diameter of up to 8mm and length of 50-80mm. There are no visible inclusions on the polished surface. The test results prove that floating zone method is an effective technology to grow GdFeO3 magneto-optical crystal.
