Growth spirals on single crystals of YBa2Cu3O7-x

Abstract

Polygonized octagonal spirals were observed on (001) surfaces of YBa2Cu3O7-x crystals grown under very pure conditions. Square spirals were more frequent on crystals grown in impure media. This difference in behavior may be related to the degree of growth step roughness. The observed forms of growth spiral are consistent with predictions based on the periodic bond chain theory.
