Abstract
The growth of single-crystal films of high-temperature superconductors of the NdBa2Cu3O7–x composition with a thickness of 1–1.5 μm on Al2O3 + CeO2 substrates during the laser spraying is investigated. Technological conditions of the epitaxial growth of the films with a temperature of superconducting transition of 95 K and a critical current of more than 106 A/cm2 at the temperature of liquid nitrogen are determined. It is shown that the structure of fabricated NdBa2Cu3O7–x films is more perfect and homogeneous than the structure of YBa2Cu3O7–x films widely used in microwave electronics.
