      abstract     = {Conventional and spin-related thermoelectric effects in
                      transport through a magnetic tunnel junction with a
                      large-spin impurity, such as a magnetic molecule or atom,
                      embedded into the corresponding barrier are studied
                      theoretically in the linear-response regime. The impurity is
                      described by the giant spin Hamiltonian, with both uniaxial
                      and transverse magnetic anisotropy taken into account. Owing
                      to the presence of the transverse component of magnetic
                      anisotropy, the spin of a tunneling electron can be reversed
                      during scattering on the impurity, even in the
                      low-temperature regime. This reversal appears due to the
                      exchange interaction of tunneling electrons with the
                      magnetic impurity. We calculate Seebeck and spin Seebeck
                      coefficients, and analyze their dependence on various
                      parameters of the spin impurity and tunnel junction. In
                      addition, conventional and spin figures of merit as well as
                      the electronic contribution to heat conductance are
                      considered. We also show that pure spin current can be
                      driven by a spin bias applied to the junction with spin
                      impurity, even if no electron transfer between the
                      electrodes can take place. The underlying mechanism employs
                      single-electrode tunneling processes (electrode-spin
                      exchange interaction) and the impurity as an intermediate
                      reservoir of angular momentum.},
