Production of a high temperature superconductor layer on a substrate for use in high energy applications comprises depositing a superconducting layer with a low growth rate

摘要

Production of a high temperature superconductor layer on a substrate comprises depositing a RBa2Cu3O7 layer (2) (where R = Y, a rare earth element of the atomic number 57-71 or a mixture of these) on the substrate (1a) using a low growth rate, and depositing a XBa2Cu3O7 layer (3) (where R = Y, a rare earth element of the atomic number 57-71 or a mixture of these) on the RBa2Cu3O7 layer using a high growth rate.
