Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a high-temperature superconducting metal material and a preparation method thereof. Background technique [0002] High-temperature superconducting materials are superconducting materials with a high critical transition temperature (Tc) that can work at the temperature of liquid nitrogen. Because it is mainly an oxide material, it is also called a high-temperature oxide superconducting material. High-temperature superconducting materials not only have a high superconducting transition temperature, but also are mostly multi-element metal oxides with copper as the main element. The oxygen content is uncertain, and they have ceramic properties. Metal elements in oxides (such as copper) may have multiple valences, and most metal elements in compounds can be completely or partially replaced by other metal elements within a certain range without losing their superconductivity. ...
