摘要：

Single crystals of CaNdAlO4 and SrLaGaO4 were used as seeds to grow large domains of YBa2Cu3Ox for levitation applications. These crystals have high melting temperatures (> 1500 degrees C) and similar lattice structures to that of YBa2Cu3Ox. In a seeded melt-texturing method developed previously, the single crystals of CaNdAlO4, SrLaGaO4, and NdBa2Cu3Ox were used as seeds for comparison. After melt processing, scanning electron microscopy analysis did not reveal any major differences in all these seeded melt-textured samples. However, the levitation forces in the samples seeded with single crystals of CaNdAlO4 and SrLaGaO4 increased considerably compared to that of the sample seeded with NdBa2Cu3Ox. A model is proposed to describe the domain growth mechanism during seeded melt processing.
