More Information
Summary:The invention relates to a series of novel Pt-doped spinel structure superconducting materials with a chemical general formula of CuRh2-xPtxSe4 (x is greater than or equal to 0 and less than or equal to 0.7) and a preparation method thereof, and belongs to the technical field of quantum function material manufacturing. According to the invention, by using a traditional high-temperature solid phase method, high-purity Cu powder, Rh powder, Pt powder and Se powder (the purity is larger than or equal to 99.9%) with the corresponding stoichiometric ratio are fully ground and then placed in a quartz tube, then vacuumizing and sealing are conducted, the sealed quartz tube containing raw materials is placed in a furnace, sintering is conducted for 240 h at a temperature of 825 DEG C to obtain CuRh2-xPtxSe4 x is larger than or equal to 0 and smaller than or equal to 0.7) polycrystalline powder, the polycrystalline powder is completely ground, tabletting is performed, a flaky sample is placed into a vacuum sealed quar
