  We obtain the covariant propagator at finite temperature for interacting
baryons immersed in a strong magnetic field. The effect of the intrinsic
magnetic moments on the Green function are fully taken into account. We make an
expansion in terms of eigenfunctions of a Dirac field, which leads us to a
compact form of its propagator. We present some simple applications of these
propagators, where the statistical averages of nuclear currents and energy
density are evaluated.
