Journal of Materials Research and Technology, Vol 28, Iss , Pp 2516-2522 (2024)
We report the effect of chemical composition variation on the superconductivity in noncentrosymmetric β-Mn-type high-entropy alloys (HEAs) studied in two very similar Ta5+xMo35−xW5Re35Ru20C20 and Ta5+yW35−yMo5Re35Ru20C20 series. It is found that

Abstract β-ThRhGe, the high-temperature polymorph of ThRhGe, is isostructural to the well-known ferromagnetic superconductor URhGe. However, contrary to URhGe, β-ThRhGe is nonmagnetic and undergoes an incomplete structural phase transition at 244 K

Iron-pnictide superconductors share similar topological band structure with iron-chalcogenide superconductors, but no Majorana modes have been observed in the former. Here, the authors observe both the superconducting Dirac surface states and Majoran
