| 中文摘要 | The subsolidus phase relations of the Sm2O3-BaO-CuO system at 950-degrees-C in air were investigated. The system can be divided into eight three-phase regions and two two-phase regions. There is one ternary compound Sm2BaCuO5, a solid solution Sm1+xBa2-xCu3Oy, and three binary compounds Sm2CuO4, BaCuO2, and Sm2BaO4. Sm2BaO4 was isolated with orthorhombic unit cell, space group Pbna, and lattice constants a = 12.313 angstrom, b = 10.535 angstrom and c = 3.564 angstrom. The solid solution range of Sm1+xBa2-xCu3Oy was determined from x = 0 to 0.4, and a phase transition from orthorhombic to tetragonal symmetry occurs at x = 0.25. With an increase in x, T(c) decreases monotonically from 94 K (onset), and the compounds of Sm1+xBa2-xCu3Oy finally become semiconducting. |
