Rapid crystal growth of triple-layered cuprate superconductor HgBa2Ca2Cu3O8+δ by cesium chloride additional method

Abstract We have developed the rapid growth method for HgBa 2 Ca 2 Cu 3 O 8+ δ (Hg-1223) by using a sealed quartz tube technique with a small amount of cesium chloride (CsCl). Our results suggested that a small amount of CsCl works as a flux during the crystal growth of Hg-1223. The developed method achieved the growth of the Hg-1223 single crystal pieces in 4 h. Furthermore, the grown single crystals showed high purity. The developed method is useful for application purposes such as high transition-temperature ( T c ) superconducting cable.
