Abstract
We investigate an AdS2 magnetic brane solution within an abelian truncation of gauged supergravity in AdS4 x orbifolded S7. The solutions flow from AdS4 -> AdS2 x R2 with a magnetic field orthogonal to the R2 directions. We find a class of supersymmetric solutions of the bulk theory to assure stability. We find the remarkable result that there exists a finite zero temperature entropy at both strong and weak coupling.
