The invention relates to a series of superconducting materials with the chemical general formula of CuIr<2-x>RuxTe4 (0.03 < = x < = 0.3) and a preparation method thereof, and belongs to the technicalfield of functional material manufacturing. The preparation method is of a traditional high-temperature
solid-phase process. The method comprises the following steps: according to a corresponding stoichiometric ratio, fully
grinding elemental Cu, ir, Ru and Te, vaccumizing and sealing a
quartz tube, then vaccumizing the
quartz tube and sealing the
quartz tube at high temperature, and finally
sintering the sealed quartz tube filled with raw materials in a furnace at 850 DEG C for 4 days to obtain polycrystalline
powder of the CuIr<2-x>RuxTe4 (0.03 < = x < = 0.3). Physical properties are testedthrough a comprehensive
physical property testing
system (PPMS) is used for determining the
superconductivity of the target product by measuring the physical properties such as
conductivity, magneticproperties and
heat capacity of the target product. This is the first reported Ru doped
tellurium-containing AB2X4 type (A, B =
metal ion, and X = O, S, Se, Te) series superconductor. By synthesizingthe compound, the application range of the AB2X4 type compound can be widened, so that the AB2X4 type compound has a huge application prospect in the aspects of
electric power, communication, high-tech equipment, military equipment and the like.
