Extreme Fermi surface smearing in a maximally disordered concentrated solid solution

Hannah C. Robarts, Thomas E. Millichamp, Daniel A. Lagos +13

We show that the Fermi surface can survive the presence of extreme compositional disorder in the equiatomic alloy Ni${}_{0.25}$Fe${}_{0.25}$Co${}_{0.25}$Cr${}_{0.25}$. Our high-resolution…
