The invention designs a series of
quantum materials with a chemical general formula of CuIr2-xAuxTe4 (x is greater than or equal to 0 and less than or equal to 0.2) and a preparation method thereof, and belongs to the technical field of
quantum functional material manufacturing. The preparation method is a traditional high-temperature
solid-
phase method and comprises the following steps: fully
grinding and mixing Cu, Ir, Au and Te
powder according to corresponding stoichiometric ratios, vacuumizing and sealing in a
quartz tube, putting the sealed vacuum
quartz tube filled with raw materials into a furnace, and
sintering at 850 DEG C for 120 hours to obtain CuIr2-xAuxTe4 (x is greater than or equal to 0 and less than or equal to 0.2) polycrystalline
powder. Physical properties such as
conductivity, magnetic property, upper and lower critical fields and the like are measured through a comprehensive
physical property test
system (PPMS), basic properties of
superconductivity and
charge density wave
phase change of a target product are deeply discussed, and a
relational graph of specific
doping concentration and respective
superconductivity and
charge density wave
phase change is established. And the
crystal structure of the target product is analyzed through XRD data fitting. With the compound
superconducting material synthesized, a new member is added for the family of
transition metal telluride superconducting materials.
