| Abstract Scope |
High entropy alloys (HEAs) are solid solutions of five or more elements in near equimolar proportions. They crystallize in simple structures and are characterized by high configurational entropy during solidification. HEAs are known for their exceptional mechanical properties, thermal stability, and corrosion resistance, so they are considered materials with high potential for applications such as high-durability mechanical devices, magnets, or superconductors. Currently, the study of HEA with uranium or thorium is mainly focused on the development of advanced high-strength materials. However, a superconducting state has also been discovered in one of the alloys, namely (TaNb)<sub>0.31</sub>(TiUHf)<sub>0.69</sub>. Here we present the crystal structure and physical properties of a high-entropy alloy (NbTa)<sub>0.67</sub>(MoWTh)<sub>0.33</sub>, which exhibits BCS superconductivity with a critical temperature of approximately 5.6-7.5 K. Additionally, we present the results of a numerical study of the electron structure of the alloy using the DFT formalism. |
