| Abstract: | A two-parameter family of supersymmetric background field solutions of the recently formulated version of gauged N = 4 supergravity is found. This constitutes strong evidence that the theory has stable vacua, despite energy densities that are unbounded below. The background geometries are metric products of (AdS)2 × S2, and there are covariantly constant magnetic and electric fields. For a special choice of parameters the (AdS)2 factor becomes a flat Minkowski space and electric fields vanish. |
