Solid-phase synthesis and properties of a large-grain high-temperature superconductor based on thulium and neodymium

Due to relative simplicity and availability of the necessary equipment, the solid-phase synthesis is the most popular way to produce new superconducting materials. This paper describes the solid-phase synthesis with the formation of sufficiently large superconducting granules. Bulk superconducting samples with the 1–2–3 structure based on thulium and neodymium with the grain size of up to 0.1 mm have been synthesized. An increase in the crystallite grain size leads to a significant increase in the trapped magnetic flux.
