Texture Analysis of Superconducting Films Based on YBCO System

Textures in different layers of superconductors based on YBCO system are analyzed using the methods of pole figure and conventional scans. It is shown that the scanning technology has only 1-dimensional description and could omit some information of 3-dimensional orientation distribution, which will influence the superconductor quality. The pole figure method, in contrast, demonstrates the orientation distribution 2-dimensionally and gives a comprehensive view of thin film texture, which is a much better method for texture analysis in superconducting films, in which there is commonly an unique high sharpness texture component.
