Abstract

Polygonized octagonal spirals were observed on (001) surfaces of YBa₂Cu₃O_7-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.
