ABSTRACT:
A method for the enhanced melt-textured growth of superconducting crystals is disclosed for a sample having a first material capable of exhibiting superconducting properties. The sample is heated above a peritectic temperature of the first material, cooled below the peritectic temperature, and is subsequently subjected to a plurality of temperature spikes in which the sample is rapidly reheated above the peritectic temperature and recooled below the peritectic temperature to produce a superconducting crystalline structure substantially free of secondary nucleations. The resulting crystal is a superconducting crystalline structure comprising a plurality of bands formed in succession around a seed material. Each band has a non-uniform microstructure from an inner portion to an outer portion of the band.
