Growth spirals on single crystals of YBa2Cu3O7-x

Published in Physica C: Superconductivity and Its Applications. 1989, vol. 157, no. 1, p. 189-191
Abstract Polygonized octagonal spirals were observed on (001) surfaces of YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7-x</sub> 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.
