Fermi surface and energy scale of disorder scattering. a Fermi surface (Γ–X–W plane) in NiCo, NiFeCo, NiFeCoCr, and NiFeCoCrMn alloys (given in arbitrary units). Majority- and minority-spin channels are distinguished using ↑ and ↓; b Magnetic origin of the energy scales for disorder scattering: Simplified depiction of the species-resolved DOS in NiFeCoCr, in which ε^σ_d denotes the 3d band centers for spin σ (σ = ↑ or ↓). The band center mismatch δ_σ is defined as max{ε^σ_d (i)}−min{ε^σ_d (i)} with i denoting different species. The exchange splitting is denoted as Δ_Exch: = ε^↓_d−ε^↑_d
