DESCRIPTION:In the past years RuO2 has emerged as a central material for u
 nderstanding the basic properties of altermagnetic materials[1]. In our wo
 rk\, we study the effects of Rh-doping on the properties of altermagnetic 
 RuO2. We use first-principles methods to simulate the effect of replacing 
 Ru atoms with Rh and study the corresponding changes in the characteristic
  spin-splitting with the Bloch vector and changes in the spin-resolved Fer
 mi surface topology. We demonstrate that the latter has a profound impact 
 on various transport characteristics of RuO2[2]. We thus promote Rh-doped 
 RuO2 as a promising platform for tuning the electronic properties and tran
 sport effects in altermagnetic materials.\n\n [1] Smejkal et al.\, Physica
