A laminated superconductor wire includes a superconductor wire assembly, which includes a first superconductor insert comprising a first high temperature superconductor layer overlaying a first substrate and a second superconductor insert comprising a second high temperature superconductor layer overlaying a second substrate. The first and second superconductor inserts are joined together at their respective substrates. An electrically conductive structure substantially surrounds the superconductor wire assembly.

Architecture for high temperature superconductor wire

A method of making a multilayer article includes depositing a first material on the surface of a metal substrate to form a seed layer of the first material, the first material being deposited under reducing conditions relative to the metal substrate, and then epitaxially depositing a second material on a surface of the seed layer, wherein the second material is deposited from a solution-based precursor under second conditions that are more oxidizing than the reducing conditions used in the deposition of the first material.

Deposition of buffer layers on textured metal surfaces

The invention relates to multi-layer articles and methods of making such articles. The multi-layer superconductors can have one or more layers with an oriented termination plane. The methods include first conditioning the termination plane of an underlying layer, such as a buffer layer or a superconductor layer, then disposing a layer of material on the conditioned termination plane. The conditioned termination plane can be a high quality termination plane. Superconductor articles formed by these methods can exhibit relatively high critical current densities.
