“…The position and diffraction peaks intensity are in good agreement with the XRD data of the Inorganic Crystal Structure Database (database code 100594, denoted as “ICSD” in Figure 1 ) [ 25 ]. The calculated unit cell parameters a = 3.48(3) and c = 18.71(6) Å correlate well with the previously reported and reference data [ 7 , 25 , 26 ]. The lattice parameters of CuCr 0.99 Ln 0.01 S 2 are close to those for CuCrS 2 -matrix and lies within the range of 3.47–3.48 and 18.67–18.71 Å for a and c , respectively.…”

“…Thus, the magnetic properties of the lanthanide-doped CuCr 1-x Ln x S 2 solid solutions are of special interest. As was previously reported, the optimal doping concentration for CuCrS 2 -based solid solutions is x = 0.01 [ 7 , 8 ]. An increase of x causes the Seebeck coefficient suppression due to the metal-insulator transition (MIT).…”

“…This results in the layered structure of CuCrS 2 that is formed by the alternating copper and dichalcogenide layers. The CuCrS 2 -based solid solutions CuCr 1-x M x S 2 are promising functional materials with thermoelectric, superionic, and magnetic properties [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. Chromium atoms could be substituted with other 3 d -metal atoms over a wide concentration range (x ≤ 0.40) without changes in the crystal structure of the initial matrix [ 6 , 11 , 12 ].…”

“…The cationic substitution of CuCrS 2 -matrix with heavier 3 d - or 4 f -metal atoms allows one to decrease the thermal conductivity due to the phonon scattering increase [ 8 , 13 , 14 ]. The reported thermoelectric properties of CuCr 1-x M x S 2 allow one to consider these compounds for the fabrication of high-performance thermoelectric generators (TEGs) [ 7 , 8 ]. The redistribution of copper atoms over the different sites in CuCr 1-x M x S 2 -structure allows one to consider CuCrS 2 -based solid solutions as promising materials for solid-state power sources, ion-selective membranes, and chemical sensors [ 6 , 15 , 16 ].…”

“…Thus, µ eff and θ lie within the wide range of values 3.8 to 5.5 µ B and −110 to −150 K, respectively. Furthermore, in case of the cation substituted solid solutions based on CuCrS 2 -matrix, the Weiss constant values are spread out even more [ 4 , 6 , 7 , 18 , 23 ]. For instance, some of the CuCrS 2 -based solid solutions were reported to have positive θ values [ 24 ].…”

The comprehensive study of the lanthanide-doped solid solutions CuCr0.99Ln0.01S2 (Ln = La…Lu) magnetic properties was carried out using static magnetochemistry and differential scanning calorimetry techniques. It was shown that magnetic properties of CuCr0.99Ln0.01S2 are significantly affected by the magnetic properties of the lanthanide ion. The magnetic susceptibility and the effective magnetic moment were found to deviate from the Curie-Weiss law in the temperature 90 K below and 50 K above the order-disorder transition at 695 K. The observed behavior of the temperature dependence of the effective magnetic moment in the order-disorder transition temperature region was described as a result of copper atoms redistribution over different types of the crystallographic sites.

When it is asked, “where can refractory metals be used?,” the possible shortest answer is, “where cannot they be used?” The uses of refractory‐metal‐based compounds in research and industry are too many to be enumerated; nevertheless, some outstanding examples are briefly mentioned here. Essentially, chalcogenide forms of refractory metals are preferred in the fabrication of high‐performance structures. Therefore, expanding the current studies that usually focus on tungsten‐ and molybdenum‐based structures to other materials may open new opportunities. Moreover, research on ternary and quaternary structures can also be a keystone in creating high‐performance products. The rationale of the present review is to give a brief overview of the recent history of refractory‐metal‐based chalcogenides (RMCs). Initially, the framework is confined to the general design and approaches for the synthesis of refractory metal chalcogenides. The assay is continued by extending with characteristic features of materials from crystalline properties to thermoelectric attributes and examining device fabrication processes. Taken together, the device fabrication part where RMCs are mainly used is extensively focused upon. Finally, outlook and future perspectives are given on the design and construction of RMCs to enable future inspiration and innovation.
