In this thesis we study the phase diagram of two-flavor quantum chromodynamics with effective models. We investigate the phase diagram in the baryon chemicalpotential temperature and magnetic field temperature planes. As approximations toQCD we use the Polyakov-loop extended quark-meson model and the Pisarski-Skokov chiral matrix model. We take quantum and thermal fluctuations of quarksinto account to one loop, while we neglect bosonic fluctuations. Bosonic self-energy cor-rections are calculated in order to consistently fix coupling constants at the one-looplevel in the large-Nc limit.
