摘要

A multilayer thin film epitaxial passivation of single crystal MgO substrates was developed. YBa₂Cu₃O_7-x films on the buffered MgO substrates demonstrate pure c-axis orientation, absence of in-plane disoriented grains, transition temperature T_c>91 K, and critical current density J_c ∼5 MA/cm² at 77.4 K and were deposited in thicknesses of up to several micrometers without cracks. High-temperature superconductor multilayer flux transformers of 2 μm thickness on the buffered MgO substrates demonstrated improved insulation between the superconducting layers and an increased dynamic range compared to flux transformers on SrTiO₃ substrates.
