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 φ scans. It is shown that the φ 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 textUr, which is a much better method for texture analysis in superconducting films, in which there is commonly an unique high sharpness texture component.
