Detecting and determining the nature of an anomalous x-ray optical effect in two-Layer substrate–coating systems

Abstract

The authors have detected an anomalous X-ray optical effect in the Ni(1−x)Wx/TiN system, which consists of a rise in the intensity of certain diffraction lines of the substrate with increasing coating thickness. Based on the observed effect, this article has conceptualized the optimization of the architecture of two-layer systems with a substrate of TiN-coated NiW paramagnetic alloys, which provides an increase in the current-carrying capacity of second generation high temperature superconductors (2G HTS).
