摘要：

A micro-pulling-down process, using Ir crucibles and RF heating, has been used to grow single-crystal fiber and bulk crystals of Tb3Ga5O12 garnet (TGG). Single crystals ranging up to 450 mm in length have been produced. The crystals were 1-4 mm in diameter and were seeded-grown in the direction close to [1 1 1]. The maximal crystal diameter achieved was 10 mm. Dependence of behavior of the solid-liquid interface on the growth parameters (temperature and pulling-rate) is discussed in detail.
