Incipient magnetism in the cubic perovskites MgCNi3 and YBRh3: A   comparison
  Using density-functional-based methods, we have studied the effects of incipient magnetism in the cubic perovskites MgCNi_{3} and YBRh_{3} . Our results show that (i) at the equilibrium volume, both MgCNi_{3} and YBRh_{3} alloys remain paramagnetic and (ii) at expanded volumes, only YBRh_{3} shows the possibility of a ferromagnetic phase with a local magnetic moment larger than 0.25 mu_{B} per Rh atom.
