Abstract

Single crystals of bismuth-calcium-strontium-copper-oxygen (BCSCO) were grown using a conventional slow-cooling flux method using KCl as a solvent. BCSCO single crystals having a surface area of about 10 mm2 were also grown by the slow-cooling method from a 4334 BCSCO melt. The composition of the thin plate-like BCSCO crystals was determined by electron beam X-ray microanalysis. Susceptibility measurements of the as-grown crystals showed the extrapolated Tc at 87 K. Polycrystalline layers up to 16 μm thickness deposited on GGG substrates from KC1 flux showed superconductivity below 85 K. According to our results this flux can be used for epitaxial growth of BCSCO superconductors.
