The equation of state of nuclear matter is strongly affected by the presence of amagnetic field. Here we study the equilibrium configuration of asymmetricnuclear matter for a wide range of densities, isospin composition, temperaturesand magnetic fields. Special attention is paid to the low density and lowtemperature domain, where a thermodynamical instability exists. Neglectingfluctuations of the Coulomb force, a coexistence of phases is found under suchconditions, even for extreme magnetic intensities. We describe the nuclearinteraction by using the non-relativistic Skyrme potential model within aHartree?Fock approach. We found that the coexistence of phases modifies theequilibrium configuration, masking most of the manifestations of the spinpolarized matter. However, the compressibility and the magnetic susceptibilityshow clear signals of this fact. Thermal effects are significative for bothquantities, mainly out of the coexistence region.
