Synthesis of a High-Temperature Superconductor Y1–xFexBa2Cu3Oy by the Sol-Gel and Solid-State Methods

Abstract

A modified version of the use of the sol-gel process at the initial stage of the synthesis of a high-temperature superconductor Y_1–xFe_xBa₂Cu₃O_y with low Fe doping is proposed. The properties of the samples obtained by sol-gel and solid-state synthesis are compared. It is shown that a more uniform distribution of the dopant throughout the volume of the sol-gel samples makes it possible to obtain materials with improved microstructural and performance characteristics.
