We present studies of spin-dependent phenomena in the non-linear energy transport through a multilevel quantum dot/molecule in the Coulomb blockade regime. Calculations are performed within the framework of non-equilibrium Green function formalism based on the equation of motion. Thermal current flowing through the system due to temperature gradient significantly varies with gate voltage. It depends on relative orientation of magnetic moments in the electrodes, so in analogy to tunneling magnetoresistance the magnetothermal conductance is introduced, which describes the effect.
