摘要：
Crystals of lanthanum gallate were grown by the Czochralski method and their quality was tested by microscopic observation in polarized light. This material is used as a substratum for the epitaxial growth of high T(c) films of YBCO, particularly for certain high-frequency device applications. Two types of twins were observed and the difference in their temperature behaviour is discussed. The best quality single crystals (practically without twins) were obtained with the [101] and [100] seeds.
