Substrates with a Cubic Texture Based on Paramagnetic Ni-W Alloy Ribbons with Thin TiN Coating for Second-Generation High-Temperature Superconductors

New ways to obtain textured substrates based on paramagnetic Ni-W alloys have been found for the creation of coated second-generation high-temperature superconductors (2G HTSs). The influence of the production conditions on texture formation in the Ni-W/TiN system has been studied for Ni-9.5 at % W alloy ribbons with TiN-based coating. It is established that optimization of the conditions of thin TiN-layer deposition makes it possible to obtain quasi-single-crystalline TiN coatings with a cubic texture. These textured Ni-W/TiN substrates admit the epitaxial growth of high-quality HTS films, which ensures high current-carrying capacity of 2G-HTS wires.
