Superconductivity in the Face Centered Cubic $\rm W_{n-x}Mo_{x}RhIrPt_{2}$ High Entropy Alloy

We report single phase superconducting face centered cubic (FCC) intermetallic high entropy alloys (HEAs) synthesized via splat cooling. The single phase materials fall at electron counts in the HEA superconductor alloy family where structural stability and optimal superconducting electron counts clash. The materials' superconducting properties follow the general trends published for metallic alloys. Many of the superconducting characteristics are summarized. Insights are provided as to why an FCC structure may be stable.
