The author prepared bulk SmBaCuO single crystals with 5×5×5mm〓 by MTG method. The SmBaCuO crystals were proved by X-ray diffraction and X-ray back-reflection Laue technique. SmBaCuO crytal became 90K zero resistance superconductor by the study of the relation of transition temperatures and heat treatment conditions.

采用MTG法及其它类似的方法制备的YBCO超导体的小样品具有很好的超导电性能，但要使YBCO超导体获得实际应用，必须制备超导电性能优异的大块YBCO超导材料，采用籽晶诱导技术是制备高性能大块YBCO超导体的有效方法，因此，制备较大尺寸高质量的〓〓单晶是籽晶诱导技术成败的关键，作者用MTG工艺制备了尺寸达5×5×5mm〓的大块〓单晶，X-ray衍射及X-ray劳埃像法证明MTG法制备的〓晶体具有很好的单晶特性。
