An (α,β)-metric is defined by a Riemannian metric α and 1-form β. In this paper, we study a known class of two-dimensional (α,β)-metrics of vanishing S-curvature. We determine the local structure of those metrics and show that those metrics are Einsteinian (equivalently, isotropic flag curvature) but generally are not Ricci-flat.
