Texture analysis of NiW alloy

Textured NiW alloy is commonly used as a substrate material for the deposition of superconducting material, either for tape fabrication or for superconducting electronics. The interaction between the weakly ferromagnetic NiW and the superconductor is important for the applications, but is sensitive to the texture of the NiW substrate.

The alloy has a cubic structure, so the (111) pole figure shows a four-fold symmetry. In addition, the beta cut across the four equivalent (111) peaks is a conventional phi-scan, a technique frequently used for rough measurement of the texture. The alpha cut across the diagonal (111) peaks is equivalent to a rocking curve scan, a widely accepted method to measure crystal quality. SmartLab enables automatic pole figure measurement, from optics alignment, sample alignment, to measurement condition setup.


The SmartLab is the most novel high-resolution diffractometer available today. Perhaps its most novel feature is the SmartLab Guidance software, which provides the user with an intelligent interface that guides you through the intricacies of each experiment. It is like having an expert standing by your side. Read more about SmartLab...
