  We study the effect of intense magnetic fields on the phase diagram of cold,
strongly interacting matter within an extended version of the
Nambu-Jona-Lasinio model that includes flavor mixing effects and vector
interactions. Different values of the relevant model parameters in acceptable
ranges are considered. Charge neutrality and beta equilibrium effects, which
are specially relevant to the study of compact stars, are also taken into
account. In this case the behavior of leptons is discussed.
