Abstract:
1. A high-temperature superconductor layer arrangement, comprising at least one substrate and one textured buffer layer comprising an oxidic buffer material permitting textured growing of a high-temperature superconductor (HTSC) layer, the buffer layer containing at least one further constituent forming a homogeneous mixed-crystal phase, wherein the further constituent comprises a metal or metal oxide that forms at least a partial melt with the oxidic buffer material at an annealing temperature of ≦1,600 degrees Celsius; wherein the further constituent is present at a concentration of 2 atom % up to 40 atom %, relative to the total metal content of the buffer layer, and wherein the further constituent and the oxidic buffer material and/or their respective precursors are deposited on the substrate separately or together as a chemical solution to provide a solution-coated substrate, and the solution-coated substrate is subjected to an annealing treatment, such that a homogeneous mixed-crystal phase containing the further constituent is formed.
