Making use of gauge/gravity duality, we study two strongly coupled field theories that are the holographic duals of SU(2) Einstein-Yang-Mills gravitational theories on asymptotically Anti-de Sitter backgrounds. One gravity setup is dual to a finite temperature field theory, while the other has a hard wall cutoff and is dual to a confining gauge theory. Both of these models undergo a superconducting phase transition at large enough values of the magnetic field. This yields a condensate in the field theory that has a ground state resembling Abrikosov vortices of a type II superconductor to linear order in perturbation theory. These models are related to p-wave superconductors where the condensate is induced by a finite isospin density. The results presented here may be of relevance to both condensed matter physics and heavy ion collisions. They may also provide support for recent proposals that the QCD vacuum may be unstable to the formation of a r meson condensate when a strong magnetic field is present.
