A modeling study highlights NiPt- and CoIr-based alloy families as the main source of its largest predicted anomalous Hall and Nernst responses. The authors propose exchange splitting, the separation between spin channels, as a way to choose parent compounds for chemical substitution. The findings are computational predictions from a virtual crystal screen.

Nominally 10% V-substituted RuO2 single crystals were uniform, metallic and paramagnetic, with 60% lower room-temperature resistivity than pristine RuO2. The authors reported no altermagnetism in the studied crystals, while calculations pointed to larger electronic changes at higher modeled substitution.
