– In this paper we consider some (α ,β ) -metrics such as generalized Kropina, Matsumoto and F (α β )2 α = + metrics, and obtain necessary and sufficient conditions for them to be Einstein metrics when β is a constant Killing form. Then we prove with this assumption that the mentioned Einstein metrics must be Riemannian or Ricci flat.
